How to get better error messages in a MAKE? - c++

Question

I run a make command on a CPP code. I get error messages like:
/home/itaymoav/dev/phpext/sitel/build/entities.cpp: In function ‘void googleset_free_storage(void*)’:
As can be seen, except showing me the entry point of the function with errors, it does not give me anymore data. Is there a flag or some other way to get proper error messages?
MakeFile -> I know it is big...

Answer 1

You will have to examine your Makefile and any rules files it includes. Find the rule for compiling .cpp into .o and see what sort of filtering it is doing on your compile output. If it is intentionally restricting the output of the compiler to make normal compiles less verbose it will probably have a flag you can set to override that. The Linux kernel (and many related Makefiles) use a QUIET flag for this purpose, so you can do make QUIET='' to disable the terse output and see everything.
If the build rule is hiding errors there is probably a bug in it. If you can find it and add it to your question someone may know how to fix it.

Answer 2

The line you quoted is not the real error message. It is just the first of two lines. The following line contains the really interesting stuff.
And only in the rare case that there isn't a second line should you worry. Because then somebody wrapped the compiler to suppress some of its error messages.
