Re: Problem of: variable `main_SOURCES' is defined but no program or library has `main' as canonical name (possible typo)

[杨觅]

Thank you Ralf,

Actually I know the rules of Makefile.am. But it just don't wokr as I
expected.

My core/Makefile.am looks like this:

bin_PROGRAMS = main
main_SOURCES = filemain.cpp

Then it returned the error msg. But if I make it like this:

lib_LTLIBRARIES = main.la
_main_la_SOURCES = filemain.cpp

Everything is OK and I am able to see the generated file main.so.

Please help me to find out the key. Thank you again for your answer :)

Cheers,
Bill
