I tried to compiled monit v5.17.1 from source code with a non-system openssl by specifying configure options, --with-ssl-incl-dir and --with-ssl-lib-dir, on my linux development box:
#1 SMP Tue Nov 3 19:10:07 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
The installation ran smoothly without any issues and from the make output I could tell the ssl libraries were found correctly from the specified locations. However, when I tried to run the monit binary I got error below:
/opt/luban/env/development.uber/.luban/pkg/monit/versions/5.17.1/bin/monit -V /opt/luban/env/development.uber/.luban/pkg/monit/versions/5.17.1/bin/monit: error while loading shared libraries: libssl.so.1.0.0: cannot open shared object file: No such file or directory
then I ran "ldd" command and confirmed that monit couldn't find libssl properly:
ldd /opt/luban/env/development.uber/.luban/pkg/monit/versions/5.17.1/bin/monit linux-vdso.so.1 => (0x00007ffd1fd99000) libm.so.6 => /lib64/libm.so.6 (0x00007ff95f747000) libpam.so.0 => /lib64/libpam.so.0 (0x00007ff95f538000) libpthread.so.0 => /lib64/libpthread.so.0 (0x00007ff95f31b000) libcrypt.so.1 => /lib64/libcrypt.so.1 (0x00007ff95f0e4000) libresolv.so.2 => /lib64/libresolv.so.2 (0x00007ff95eeca000) libnsl.so.1 => /lib64/libnsl.so.1 (0x00007ff95ecb0000) libssl.so.1.0.0 => not found libcrypto.so.1.0.0 => not found libc.so.6 => /lib64/libc.so.6 (0x00007ff95e8ee000) libaudit.so.1 => /lib64/libaudit.so.1 (0x00007ff95e6c7000) libdl.so.2 => /lib64/libdl.so.2 (0x00007ff95e4c3000) /lib64/ld-linux-x86-64.so.2 (0x00007ff95fa51000) libfreebl3.so => /lib64/libfreebl3.so (0x00007ff95e2bf000)
I then tried installing monit with the system openssl and the installation was successfully, monit could run properly without any errors like above.
Therefore, I suspect the given ssl header and lib locations were not properly handled in run-time although they were used during compilation.
Feel free to let me know if you want me to provide extra information.
Thank you very much!
