Linker issue with Xcode4 building axis2/c library

Question

I'm building a simple c library using the axis2/c webservices framework. I can get my library to build using gcc at the command line, but am having difficulties configuring my project successfully in Xcode4.

The following build at the command line works:

gcc -shared -o liblatlon2pcde.so -I$AXIS2C_HOME/include/axis2-1.6.0/ \ 
    -L$AXIS2C_HOME/lib -laxutil -laxis2_axiom -laxis2_parser -laxis2_engine \
    -lpthread -laxis2_http_sender -laxis2_http_receiver latlon2pcde.c \
    latlon2pcde_skeleton.c

In Xcode4 I've configured by build settings similarly

User- defined

AXIS2C_HOME    /usr/local/axis2c

Header Search Paths

${AXIS2C_HOME}/include/axis2-1.6.0

Library Search Paths

${AXIS2C_HOME}/lib

Other linker flags

-laxutil -laxis2_axiom -laxis2_parser -laxis2_engine -lpthread -laxis2_http_sender -laxis2_http_receiver

However the build fails reporting that -laxutil could not be found

ld: library not found for -laxutil
Command /Developer/usr/bin/clang failed with exit code 1

The full output is:

Build target latlon2pcde

So it looks like my library search path isn't making its way into the linker. Any ideas why?

Answer 1

Mystery solved. Seems like this was an issue with the "Project" and "Target" settings diverging, ie I'd changed one but not the other. I started with fresh build settings, reapplied as described in my original post and all works. If in doubt "turn it off and turn it back on again"!

Answer 2

Add the header search and library search paths explicitly, in place of ${AXIS2C_HOME}. It's rubbish, but it should work.
