[Cppcms-users] Build cppcms-0.99.5

[hce <web...@gm...>]

Hi,

I am building cppcms-0.99.5 with non-standardard pcre and libgcrypt
location. I set up pcre and libgcrypt in ldconfig, but I've still got
error  of "undefined reference to `pcre_fullinfo" and "undefined
reference to `gcry_cipher_setkey". Is there any way to set up pcre and
libgcrypt in cmake configuration files?

Thank you.

Fist of all you need make sure you specify the path to the 
location of these files in CMake

cmake -DCMAKE_INCLUDE_PATH="/opt/myprce/include;/opt/mygcrypt/include" \
      -DCMAKE_LIBRARY_PATH="/opt/myprce/lib;/opt/mygcrypt/lib" \
      (other options)


Then make sure that CMake finds what you need. i.e.:

Take a look on your CMakeCache.txt

It should be contain likes that look like this:

//Path to a file.
PCRE_INCLUDE:PATH=/opt/myprce/include

//Path to a library.
PCRE_LIB:FILEPATH=/opt/myprce/lib/libpcre.so

//Path to a file.
GCRYPT_INCLUDE_DIR:PATH=/opt/mygcrypt/include

//Path to a library.
LIB_GCRYPT:FILEPATH=/opt/mygcrypt/lib/libgcrypt.so


And not pointing to standard location /usr/lib/libpcre.so

Are these the only functions you miss and other don't 
like gcry_cipher_encrypt and pcre_compile?

If so can this be an issue with your specific build of these libraries
that miss these functions, or it may be that CMake searches for the libraries
in standard location rather in the location you need.

You can specify the variables above manually, i.e. 

cmake \ 
   -DPCRE_INCLUDE:PATH=/opt/myprce/include \
   -DPCRE_LIB:FILEPATH=/opt/myprce/lib/libpcre.so \
   -DGCRYPT_INCLUDE_DIR:PATH=/opt/mygcrypt/include \
   -DLIB_GCRYPT:FILEPATH=/opt/mygcrypt/lib/libgcrypt.so \
   ..

However first method is recommended (with specification if 
CMAKE_INCLUDE_PATH/CMAKE_LIBRARY_PATH

Best,
  Artyom

Thanks Artyom, that is exactly what I was looking for, works well.
