Thank you Eljay. Your hint helped me to find the problem. nm recognizes functions lib1.a, but complains that "File format not recognized" for files in lib2.a. Files in lib1 (*.c) were written in C, but files (*.cpp) in lib2 were written in c++ and compiled with g++. I changed all compilers/linkers to g++, still has the problem. Don't tell me I have to convert all the functions in lib2 into C format. :-) Kevin -----Original Message----- From: John Love-Jensen [mailto:eljay@xxxxxxxxx] Sent: Tuesday, March 28, 2006 1:25 PM To: Kevin Ma; MSX to GCC Subject: Re: linking libraries by gcc Hi Kevin, > The functions (that gcc said undefined reference to) are defined in lib2.a. > They are called by lib1.a. Hmmm. Then the linker should be able to find them. Very strange. Can you do a nm on lib1.a and lib2.a to verify that the missing symbols are 'U' in lib1.a and 'T' in lib2.a. Thanks, --Eljay
