Hi,

I am trying to compile Apache 2.4.1 with openssl 1.0.1 on Linux 2.6.32-71.el6.x86_64.
Following is the last block of the 'make' command of apache.

make[4]: Entering directory `/root/shishir/httpd-2.4.1/modules/ssl'
/root/shishir/httpd-2.4.1/srclib/apr/libtool --silent --mode=link gcc -std=gnu99 -g -O2 -pthread -o mod_ssl.la -rpath /usr/pw/apache/modules -module -avoid-version mod_ssl.lo ssl_engine_config.lo ssl_engine_dh.lo ssl_eng

collect2: ld returned 1 exit status
make[4]: *** [mod_ssl.la] Error 1
make[4]: Leaving directory `/root/shishir/httpd-2.4.1/modules/ssl'



Please note, make test for openssl came successful.

Please suggest what can be wrong while reading libssl.a?

Thanks,
Shishir

For me it worked only when I installed OpenSSL in the system and used that.

See in your error message? /usr/pw/apache/openssl/lib/libssl.a that is not /root/shishir/httpd-2.4.1/srclib/openssl

Code: [Select]

wget http://openssl.org/source/openssl-1.0.1.tar.gz
 tar xfz openssl-1.0.1.tar.gz
 cd openssl-*
 ./config --prefix=/usr zlib-dynamic --openssldir=/etc/ssl shared
 make
 sudo make install


Code: [Select]

./buildconf
./configure --prefix=/opt/apache2 --enable-pie --enable-mods-shared=all --enable-so --disable-include --enable-deflate --enable-headers --enable-expires --enable-ssl=shared --enable-mpms-shared=all --with-mpm=event --enable-rewrite --with-z=/home/mario/apache24/httpd-2.4.2/srclib/zlib --enable-module=ssl --enable-fcgid --with-included-apr


[shishir]

i have used the following..
for openssl
./config no-threads --prefix=/usr/pw/apache/openssl
make
make install

for httpd2.4.1
./configure --prefix=/usr/pw/apache --with-ssl=/usr/pw/apache/openssl --enable-ssl=shared --enable-mods-shated=most
--with-expat=builtin --with-included-apr --with-pcre=/root/shishir/pcre-8.30/pcre-config

is this wrong? or require some correction?
is zlib required here?

[mario]

zlib is for mod deflate needed.

For openssl you may try

Code: [Select]

./config no-threads shared --prefix=/usr/pw/apache/openssl
cause your error message says: recompile with -fPIC that is the shared option for gcc

[shishir]

Thanks for the inputs, tried as suggest
./config no-threads shared --prefix=/usr/pw/apache/openssl

and got a new error

/usr/bin/ld: libcrypto.a(e_4758cca.o): relocation R_X86_64_32 against `.data' can not be used when making a shared object; recompile with -fPIC
libcrypto.a(e_4758cca.o): could not read symbols: Bad value

[mario]

Did you run make clean before trying?

by the way, which Linux are you using?

[shishir]

yea it worked for that phase..thanks for the tip.

but this time i can see mod_ssl.so in my \apache\modules list but when i try to start the apache it is throwing the below error.

httpd: Syntax error on line 155 of /usr/pw/apache/conf/httpd.conf: Cannot load /usr/pw/apache/modules/mod_ssl.so into server: /usr/pw/apache/modules/mod_ssl.so: undefined symbol: SSL_SESSION_get_compress_id

Any suggestions on this?

I'm seeing this same error on RHEL6.2, with openssl 1.0.1c and Apache 2.4.1:

httpd: Syntax error on line 33 of /usr/local/apache/conf/httpd.conf: Cannot load /usr/local/apache/modules/mod_ssl.so into server: /usr/local/apache/modules/mod_ssl.so: undefined symbol: SSL_SESSION_get_compress_id

Does anyone have any idea what I can do to solve this?

Thanks,
Paul

[paulnorwich]

I discovered my problem was that at runtime this was linking to my OS's openssl libraries rather than the openssl I'd built in /usr/local/openssl

export LD_LIBRARY_PATH=/usr/local/openssl/lib

then running apache fixed it.

Hi Shishir, I'm getting this error too. I found your post after pasting the error into google. Do you know what this code means and how to get rid of it? Thanks.

[mario]

Yes the issue can be solved by export LD_LIBRARY_PATH=/usr/local/openssl/lib

You can see an example in https://github.com/JBlond/debian_build_apache24

[tomahawk]

Yes the issue can be solved by reading about the 4 Minutes Fighter Abs export LD_LIBRARY_PATH=/usr/local/openssl/lib

You can see an example in https://github.com/JBlond/debian_build_apache24

Thank you very much Mario, github very useful. Thanks

[sarajames]

Thank you, yes! Finally figured out how to solve my compiling issue with Apache!

Much appreciated, Sara

I found this post by searching google for my problem, i used the github recommendation to solve the problem but now my computer is freezing everytime i run anything, i'm starting to think this is beyond me 

how is your folder structure? How did you configure your apache build?

it seems that your apache is compiled against a different OpenSSL version than it was compiled against.
