Hi,
I am trying to gprof my program. I want a line-by-line profiling.
However, I can't seem to get the syntax write. I am using "make" and not "gcc" so please help only with suggestions that fit make. I wouldbe very grateful if you can give me the full "make" syntax.
Based on this website:
http://sourceware.org/binutils/docs/gprof/Output-Options.html[^]
http://sourceware.org/binutils/docs/gprof/Line_002dby_002dline.html[^]
Here is what I am inputting:
make USE_LOCAL_HEADERS=0 LDFLAGS='-L.' BASE_CFLAGS=-m32 CFLAGS='-fopenmp -pg -l -g'
The output is:

VB

/usr/bin/ld: cannot find -l-g
collect2: ld returned 1 exit status
make[2]: *** [build/release-linux-ppc64/ioquake3.ppc64] Error 1
make[2]: Leaving directory `/r/home7/yasir/minoru/cfe2/yasirTemp/ioquake3dev/svfb_201110271440/ioquake3dev_clean'
make[1]: *** [targets] Error 2
make[1]: Leaving directory `/r/home7/yasir/minoru/cfe2/yasirTemp/ioquake3dev/svfb_201110271440/ioquake3dev_clean'
make: *** [release] Error 2

I need option "-l", "-g" and "-pg".

Regards,
Linux noob

Solution 1

The '-l' option is not valid for gcc so it assumes that it, and all following options, should be passed to the linker. You need to check which options are valid for gprof, as described here[^], and for gcc as described here[^].

"make USE_LOCAL_HEADERS=0 LDFLAGS='-L. -pg' BASE_CFLAGS=-m32 CFLAGS='-fopenmp -pg -g'" is how it got operative now. So, as you kindly said, "-l" was not valid. Thank you for the help.
