Hi,
two attachments: 1. gcrt0.o (just copy into /lib).
2. specs (just copy into /lib/gcc-lib/i386-gnu/2.95.4/)
The path to the gcc files depends on the version number.
Usage:
To profile the program only:
$ gcc -o main main.c -pg
$ ./main
$ gprof main gmon.out
To profile the program and the C library:
$ gcc -o main main.c -profile
$ ./main
$ gprof main gmon.out
The specs file implement the following option combinations:
Notes: -shared overrides (and prevents) profiling options.
-profile forces to link the profiling C library statically
-pg/-p does link to the normal C library (dynamically or statically)
static shared pg p profile =>lib
Y/N N Y/N Y/N N -lc
N Y Y/N Y/N Y/N -lc
Y/N N Y/N Y/N Y -lc_p
static shared pg p profile =>startfile
N N N N N crt1.o crti.o crtbegin.o
Y N N N N crt0.o crti.o crtbegin.o
N Y Y/N Y/N Y/N crti.o crtbeginS.o
N N Y/N Y/N Y gcrt0.o crti.o crtbegin.o
Y N Y/N Y/N Y/N gcrt0.o crti.o crtbegin.o
^^^^^^^^^^^^^^^^^^^ at least one Y
N N Y/N Y/N N gcrt1.o crti.o crtbegin.o
^^^^^^^^^^^ at least one Y
Thanks,
Marcus
