[Cppcms-users] Booster-PCRE linking

[Sab <rim...@gm...>]

Hi Artyom,

I'm cross compiling my application and having trouble with linking the 
static libraries. CppCMS compiles fine but when I compile my application 
that uses cppcms, I get undefined reference to 'pcre_exec', 'pcre_compile' 
and 'pcre_fullinfo' needed by libbooster.a e.g. in function 
'booster::regex::match'. 

Here is how I compile CppCMS in my environment installer Makefile:

Shared3rdParty/cppcms-1.0.2.target/pub/libcppcms.a: 
	Shared3rdParty/zlib-1.2.7.target/pub/lib/libz.a
	Shared3rdParty/pcre-8.32.target/pub/lib/libpcre.a
	cd Shared3rdParty/cppcms-1.0.2.target && mkdir -p -v build
	cd Shared3rdParty/cppcms-1.0.2.target/build && cmake \
		-DCMAKE_TOOLCHAIN_FILE="../../Product/gcc-${TOOLSUITE}.cmake" \
		-DCMAKE_BUILD_TYPE=MinSizeRel \
		-DDISABLE_ICU_LOCALE=ON \
		-DDISABLE_POSIX_LOCALE=ON \
		-DDISABLE_SHARED=ON \
		-DDISABLE_GCRYPT=ON \
		-DDISABLE_OPENSSL=ON \
		-DDISABLE_OPENSSL=ON \
		-DCMAKE_INSTALL_PREFIX="../pub" \
		-DDISABLE_SCGI=ON \
		-DDISABLE_HTTP=ON \
		-DZLIB_INCLUDE_DIR="../../zlib-1.2.7.target/pub/include" \
		-DZLIB="../../zlib-1.2.7.target/pub/lib/libz.a" \
		-DPCRE_LIB="../../pcre-8.32.target/pub/lib/libpcre.so" \
		-DCMAKE_INCLUDE_PATH="../../pcre-8.32.target/pub/include" \
		-DCMAKE_LIBRARY_PATH="../../pcre-8.32.target/pub/lib" ..
	cd Shared3rdParty/cppcms-1.0.2.target/build && make && make install

Here is how I compile pcre in the same makefile:

Shared3rdParty/pcre-8.32.target/pub/lib/libpcre.a:
	cd Shared3rdParty/pcre-8.32.target && ./configure --host=${TOOLSUITE} 
--prefix=`pwd`/pub 
	cd Shared3rdParty/pcre-8.32.target && make && make install
	

I do see the right path in CppCMS's CMakeCache.txt:

//Path to a library.
PCRE_LIB:FILEPATH=/work/eBox/Shared3rdParty/pcre-8.32.target/pub/lib/libpcre.so

and:

//Dependencies for the target
booster-static_LIB_DEPENDS:STATIC=general;
/usr/arm-linux-gnueabi/lib/libpthread.so;
general;
/work/eBox/Shared3rdParty/pcre-8.32.target/pub/lib/libpcre.so;general;
/usr/arm-linux-gnueabi/lib/libdl.so;


The pcre lib compiles fine and it is in the right path. 
Cppcms uses the right path too. 
Why isn't pcre get linked correctly to booster?

Is it still relevant?

What usually you do is not to specifiy explicitly the PCRE path but rather let CMake find it,
 

        -DCMAKE_INCLUDE_PATH="../../pcre-8.32.target/pub/include" \
        -DCMAKE_LIBRARY_PATH="../../pcre-8.32.target/pub/lib:zlib-1.2.7.target/pub" ..

Without ZLIB=... PCRE_LIB= etc.

Note it is also to run make install in PCRE and ZLIB - install them to a single location with all correct files and libraries and THAN use rater
than pointing to source directories.

Also it seems that you are mixing shared and static libraries (../../pcre-8.32.target/pub/lib/libpcre.so")
