C compiler not working

Tried to run minicom onred hat enterprise 5.2, but this failed because gcc was not installed. Installed gcc, but now when I do ./configure, i get the following error:

checking for a BSD-compatible install... /usr/bin/install -c
checking whether build environment is sane... yes
checking for a thread-safe mkdir -p... /bin/mkdir -p
checking for gawk... gawk
checking whether make sets $(MAKE)... yes
checking for gcc... gcc
checking whether the C compiler works... no
configure: error: in `/home/admin/minicom-2.6.1':
configure: error: C compiler cannot create executables
See `config.log' for more details

Can someone help me figure out what is going on here?

Create a simple c program and try to compile it. See what kind of error it gives you.

hello.c

Code:

#include <stdio.h>



main()

{

  printf("Hello World\n");

}

compile with: gcc hello.c

so...

Code:

See `config.log' for more details

It might throw some light into the issue. This can happen for many reasons, from an unconfigured environment to the wrong CFLAGS.

How did you install gcc?

Here's a partial output of the config log:

This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by minicom configure 2.6.1, which was
generated by GNU Autoconf 2.68. Invocation command line was

gcc installed from the following link through firefox:

http://rpmfind.net/linux/rpm2html/se...rise+5.2&arch=

looks like the linker can't find a required library:

ld: crt1.o: No such file: No such file or directory

That file should be in /usr/lib. Try to re-install the compiler or find another package.

I haven't used minicom in over 15 years, brings back memories.

Do you know any good package that I can use?

Any reason you are building from source? I see a minicom for Redhat 4 i386

It's VERY rare that you need to install directly from the RPM, especially for something as core as gcc. Chances are you installed gcc, but none of the libraries that it needs, which is why it doesn't work. Use YUM for this kind of thing.

I would start by removing the RPM you installed by hand, and issue a "yum install gcc" or similar. YUM probably has minicom as well:

Code:

yum list | grep -i minicom

Any time you want a program in any of the Redhat-based distros (RHEL, CentOS, Fedora), start by doing a "yum list | grep" to find if it's in yum. If it isn't, find the source. When you go to configure/compile the source, if you encounter any missing libraries or programs, again use yum to find and install them. 99% of the time you can use "yum provides" to find your missing library/binary.

Installed gcc

The default "Redhat EL 5.x" compiler is version 4.1.2.
( gcc version 2.7.2.3 is usually totally unusable for an OS from this century.)

Required packages, for gcc to be usable :
gcc, gcc-c++, glibc-devel-2.5-24, glibc-headers-2.5-24, kernel-headers-2.6.18-92
The shown versions are the old RHEL 5.2 versions.
Can be installed from your install DVD.
If you can use yum, glibc will be updated to version 2.5-81.el5_8.1.

.

Thanks! I will try that.
