help with installing gcc

Geminias · 01-04-2006, 06:45 PM

to my knowledge, it is possible to have your system set up to accept the command "gcc program.cpp -o program.exe" and this command will compile c++ source.

this is all i want, and for god sakes i can't manage to accomplish it.

i installed (i think) gcc.. here's what i have lol.. (yes i'm total noob)

Code:

[root@localhost ~]# cd /
[root@localhost /]# cd /usr/src/redhat/SOURCES
[root@localhost SOURCES]# ls

you are trying to compile a windows exe on ur linux box?

It looks like you installed a source RPM for gcc, which is why you see things in /usr/src. You need a binary RPM to install, since you need gcc to compile gcc (chicken and egg). You should be able to find one on your install media.

what you are seeing are some of gcc's freinds and family
compile something using the -v switch and you see it all
as example i type
gcc -v -o dsp_info dsp_info.c
first thing it does is this
/usr/lib/gcc/i686-pc-linux-gnu/3.4.1/cc1 -quiet -v dsp_info.c -quiet -dumpbase dsp_info.c -mtune=pentiumpro -auxbase dsp_info -version -o /tmp/cc4pXJBa.s

compilers are complicaed things
i think cc1 might be whats called a stub program ?
it's doing some of the work of converting the code into whats understood by the assembler or something
