Hello, I am having difficulty linking using make created by Eclipse CDT. My setup is the following: - Mac Intel Code 2 Duo - OS X 10.5.4 (fully patched) - XCode 3.1 - Eclipse 3.4 (Ganymede) CDT - Darwin ports 1.6.0 - cppunit 1.12.1 So cppunit libraries are located in /opt/local/lib/ and the header files are located in /opt/local/include here is the result on the make session **** Build of configuration Debug for project mycpptest **** make all Building file: ../src/main.cpp Invoking: GCC C++ Compiler g++ -I/opt/local/include -O0 -g3 -Wall -c -fmessage-length=0 -MMD -MP -MF"src/main.d" -MT"src/main.d" -o"src/main.o" "../src/main.cpp" Finished building: ../src/main.cpp Building target: mycpptest Invoking: MacOS X C++ Linker g++ -L/opt/local/lib -o "mycpptest" ./src/main.o -llibcppunit.a ld: library not found for -llibcppunit.a collect2: ld returned 1 exit status make: *** [mycpptest] Error 1 The file libcppunit.a is really located in /opt/local/lib, I have verified. I have tried multiple combinasons with the -L and -l parameters with no success For some reasons, the linker does not seems to like the library ??? Any suggestions ... Thanks Sylvain PS: To validate the code and library I have created a project using XCode and the file compile, link and run correctly.
