1 * System libcrypto.dylib and libssl.dylib are used by system ld on MacOS X.
4 NOTE: The problem described here only applies when OpenSSL isn't built
5 with shared library support (i.e. without the "shared" configuration
6 option). If you build with shared library support, you will have no
7 problems as long as you set up DYLD_LIBRARY_PATH properly at all times.
10 This is really a misfeature in ld, which seems to look for .dylib libraries
11 along the whole library path before it bothers looking for .a libraries. This
12 means that -L switches won't matter unless OpenSSL is built with shared
15 The workaround may be to change the following lines in apps/Makefile and
18 LIBCRYPTO=-L.. -lcrypto
23 LIBCRYPTO=../libcrypto.a
26 It's possible that something similar is needed for shared library support
27 as well. That hasn't been well tested yet.
30 Another solution that many seem to recommend is to move the libraries
31 /usr/lib/libcrypto.0.9.dylib, /usr/lib/libssl.0.9.dylib to a different
32 directory, build and install OpenSSL and anything that depends on your
33 build, then move libcrypto.0.9.dylib and libssl.0.9.dylib back to their
34 original places. Note that the version numbers on those two libraries
35 may differ on your machine.
38 As long as Apple doesn't fix the problem with ld, this problem building
39 OpenSSL will remain as is.
42 * Parallell make leads to errors
44 While running tests, running a parallell make is a bad idea. Many test
45 scripts use the same name for output and input files, which means different
46 will interfere with each other and lead to test failure.
48 The solution is simple for now: don't run parallell make when testing.
51 * Bugs in gcc triggered
53 - According to a problem report, there are bugs in gcc 3.0 that are
54 triggered by some of the code in OpenSSL, more specifically in
55 PEM_get_EVP_CIPHER_INFO(). The triggering code is the following:
58 if (*header != '4') return(0); header++;
59 if (*header != ',') return(0); header++;
61 What happens is that gcc might optimize a little too agressively, and
62 you end up with an extra incrementation when *header != '4'.
64 We recommend that you upgrade gcc to as high a 3.x version as you can.
66 - According to multiple problem reports, some of our message digest
67 implementations trigger bug[s] in code optimizer in gcc 3.3 for sparc64
68 and gcc 2.96 for ppc. Former fails to complete RIPEMD160 test, while
71 The recomendation is to upgrade your compiler. This naturally applies to
74 - There is a subtle Solaris x86-specific gcc run-time environment bug, which
75 "falls between" OpenSSL [0.9.8 and later], Solaris ld and GCC. The bug
76 manifests itself as Segmentation Fault upon early application start-up.
77 The problem can be worked around by patching the environment according to
78 http://www.openssl.org/~appro/values.c.
80 * solaris64-sparcv9-cc SHA-1 performance with WorkShop 6 compiler.
82 As subject suggests SHA-1 might perform poorly (4 times slower)
83 if compiled with WorkShop 6 compiler and -xarch=v9. The cause for
84 this seems to be the fact that compiler emits multiplication to
85 perform shift operations:-( To work the problem around configure
86 with './Configure solaris64-sparcv9-cc -DMD32_REG_T=int'.
88 * Problems with hp-parisc2-cc target when used with "no-asm" flag
90 When using the hp-parisc2-cc target, wrong bignum code is generated.
91 This is due to the SIXTY_FOUR_BIT build being compiled with the +O3
92 aggressive optimization.
93 The problem manifests itself by the BN_kronecker test hanging in an
94 endless loop. Reason: the BN_kronecker test calls BN_generate_prime()
95 which itself hangs. The reason could be tracked down to the bn_mul_comba8()
96 function in bn_asm.c. At some occasions the higher 32bit value of r[7]
97 is off by 1 (meaning: calculated=shouldbe+1). Further analysis failed,
98 as no debugger support possible at +O3 and additional fprintf()'s
99 introduced fixed the bug, therefore it is most likely a bug in the
101 The bug was found in the BN_kronecker test but may also lead to
102 failures in other parts of the code.
105 Workaround: modify the target to +O2 when building with no-asm.
107 * Problems building shared libraries on SCO OpenServer Release 5.0.6
110 The symptoms appear when running the test suite, more specifically
111 test/ectest, with the following result:
113 OSSL_LIBPATH="`cd ..; pwd`"; LD_LIBRARY_PATH="$OSSL_LIBPATH:$LD_LIBRARY_PATH"; DYLD_LIBRARY_PATH="$OSSL_LIBPATH:$DYLD_LIBRARY_PATH"; SHLIB_PATH="$OSSL_LIBPATH:$SHLIB_PATH"; LIBPATH="$OSSL_LIBPATH:$LIBPATH"; if [ "debug-sco5-gcc" = "Cygwin" ]; then PATH="${LIBPATH}:$PATH"; fi; export LD_LIBRARY_PATH DYLD_LIBRARY_PATH SHLIB_PATH LIBPATH PATH; ./ectest
116 The cause of the problem seems to be that isxdigit(), called from
117 BN_hex2bn(), returns 0 on a perfectly legitimate hex digit. Further
118 investigation shows that any of the isxxx() macros return 0 on any
119 input. A direct look in the information array that the isxxx() use,
120 called __ctype, shows that it contains all zeroes...
122 Taking a look at the newly created libcrypto.so with nm, one can see
123 that the variable __ctype is defined in libcrypto's .bss (which
124 explains why it is filled with zeroes):
126 $ nm -Pg libcrypto.so | grep __ctype
130 Curiously, __ctype2 is undefined, in spite of being declared in
131 /usr/include/ctype.h in exactly the same way as __ctype.
133 Any information helping to solve this issue would be deeply
136 NOTE: building non-shared doesn't come with this problem.
138 * ULTRIX build fails with shell errors, such as "bad substitution"
139 and "test: argument expected"
141 The problem is caused by ULTRIX /bin/sh supporting only original
142 Bourne shell syntax/semantics, and the trouble is that the vast
143 majority is so accustomed to more modern syntax, that very few
144 people [if any] would recognize the ancient syntax even as valid.
145 This inevitably results in non-trivial scripts breaking on ULTRIX,
146 and OpenSSL isn't an exclusion. Fortunately there is workaround,
147 hire /bin/ksh to do the job /bin/sh fails to do.
149 1. Trick make(1) to use /bin/ksh by setting up following environ-
150 ment variables *prior* you execute ./Configure and make:
154 export PROG_ENV MAKESHELL
156 or if your shell is csh-compatible:
158 setenv PROG_ENV POSIX
159 setenv MAKESHELL /bin/ksh
161 2. Trick /bin/sh to use alternative expression evaluator. Create
162 following 'test' script for example in /tmp:
167 Then 'chmod a+x /tmp/test; ln /tmp/test /tmp/[' and *prepend*
168 your $PATH with chosen location, e.g. PATH=/tmp:$PATH. Alter-
169 natively just replace system /bin/test and /bin/[ with the
172 * hpux64-ia64-cc fails blowfish test.
174 Compiler bug, presumably at particular patch level. It should be noted
175 that same compiler generates correct 32-bit code, a.k.a. hpux-ia64-cc
176 target. Drop optimization level to +O2 when compiling 64-bit bf_skey.o.
178 * no-engines generates errors.
180 Unfortunately, the 'no-engines' configuration option currently doesn't
181 work properly. Use 'no-hw' and you'll will at least get no hardware
182 support. We'll see how we fix that on OpenSSL versions past 0.9.8.
184 * 'make test' fails in BN_sqr [commonly with "error 139" denoting SIGSEGV]
185 if elder GNU binutils were deployed to link shared libcrypto.so.
187 As subject suggests the failure is caused by a bug in elder binutils,
188 either as or ld, and was observed on FreeBSD and Linux. There are two
189 options. First is naturally to upgrade binutils, the second one - to
190 reconfigure with additional no-sse2 [or 386] option passed to ./config.
192 * If configured with ./config no-dso, toolkit still gets linked with -ldl,
193 which most notably poses a problem when linking with dietlibc.
195 We don't have framework to associate -ldl with no-dso, therefore the only
196 way is to edit Makefile right after ./config no-dso and remove -ldl from
