C error?
Hi @ll,
When I try to run any configure file obtaind the following message
checking build system type... i586-pc-linux-gnu
checking host system type... i586-pc-linux-gnu
checking target system type... i586-pc-linux-gnu
checking for a BSD compatible install... /usr/bin/install -c
checking whether build environment is sane... yes
checking for mawk... no
checking for gawk... gawk
checking whether make sets ${MAKE}... yes
checking for gcc... gcc
checking for C compiler default output... configure: error: C compiler

My machine RH6.2 whit this package:

I'm not C expert, any idea?
TIA

I typically get this error when I have configured GCC as a cross compiler
of some sort (for a different set of system libraries or for a different
CPU/Architecture). If it's a typical configure script then it means just
what it says it means, the script tried to compile a program (and probably
it compiled correctly) but then was unable to execute the output. Another
common cause of this is if for some reason your C compiler is not producing
output with the execute bit set by default. This can happen either if you
have a umask problem, or if you are running a script on a mounted
filesystem that doesn't support it (any read-only filesystem, any FAT
(DOS/Windows) filesystem, etc.). A good way to test this is to create a
little hello world program that requires dynamic linking, and see if you
can compile it and execute in the current directory. Something like:
--- CUT HERE ---
#include stdio.h
#include math.h
int main() {
double foo;
foo = 4.3;
foo = sin( foo );
printf( Sin(4.3) = %lf\n, foo );
return 0;
}
--- CUT HERE ---
Save that (in the same dir as the configure script) as hello.c then run
gcc -Wall -g -lm hello.c
To compile it and link it against the math library. It should create an
executable file called a.out, so you should then be able to run
./a.out
And see the output:
Sin(4.3) = -0.916166
And then you can safely delete hello.c and a.out. If all of this works then
the configure script you're trying to run is broken. Typical places I can
think of where it would fail:
If the compiler says something about being unable to include math.h, or
tells you that you have an implicit definition of anything, then your
header files and/or libraries are not installed correctly.
If the compiler tells you it is unable to resolve the reference to the
sin() function then your header files are probably fine, but your linker
and/or library files are screwed up.
If the program compiles successfully and when you run it you get an error
like file not found then you are probably configured to link (at compile
time) against a different set of libraries from those actually available at
run-time (usually because you've been cross-compiling for some other machine).
ls -al a.out should show you something like:
-rwxr-xr-x1 cnww users 21975 Mar 4 17:25 a.out
If the program compiles, but doesn't appear executable (i.e. the x bits
are not set in ls output) then you have a problem with the configuration of
the current directory.

You also need a number of -devel packages. At least get glibc-devel and kernel-headers installed and try again. ___ Redhat-list mailing list [EMAIL PROTECTED] https://listman.redhat.com/mailman/listinfo/redhat-list

I'm not C expert, any idea? I don't think it has anything to do with C, but rather your environment. Could be a umask issue (just a thought). Your environment might prefent you from setting files as executable. ___ Redhat-list mailing list [EMAIL PROTECTED] https://listman.redhat.com/mailman/listinfo/redhat-list

To me, it looks like you're missing the package that contains the
assembler, In RedHat 7.1 it's called dev86-0.15.0-5.
