Unable to compile on centos 7.4 : error: expected ‘,’ or ‘;’ before ‘typedef’

[darksniperx]

As soon as i upgraded to centos 7.4, i was not able to compile any packages. Whether it was python package , ffmpeg, gcc,..

The issue is generally on fresh install of 7.4


All packages give the same error: "error: expected ‘,’ or ‘;’ before ‘typedef’"

sample output when trying to compile ffmpeg:

sudo make V=1

Please provide the output of

rpm -q glibc-headers
rpm -V glibc-headers (this may be empty)

Also, unable to reproduce:

Code: Select all

$ cat test.c
#include <stdio.h>
#include <math.h>

int main(int argc, char *argv[]) {
	printf("Hello world\n");
	return 0;
}
$ make test
cc     test.c   -o test
$ ./test
Hello world
$ rpm -q glibc glibc-headers gcc make
glibc-2.17-196.el7.x86_64
glibc-headers-2.17-196.el7.x86_64
gcc-4.8.5-16.el7.x86_64
make-3.82-23.el7.x86_64

I tried to reproduce too and failed though mine helloworld.c also included the same typedef float float_t; line from the original report.

Forgot to mention, the issue is generally on fresh install of 7.4

rpm -q glibc-headers: glibc-headers-2.17-196.el7.x86_64

rpm -V glibc-headers: (blank)

rpm -q glibc glibc-headers gcc make:
glibc-2.17-196.el7.x86_64
glibc-2.17-196.el7.i686
glibc-headers-2.17-196.el7.x86_64
gcc-4.8.5-16.el7.x86_64
make-3.82-23.el7.x86_64

Just trying to help, found this thread interesting my default 7.4 shows following:

Code: Select all

[dlazov@zovs-centos7 hello]$ make test
cc     test.c   -o test
[dlazov@zovs-centos7 hello]$ ./test
Hello world
[dlazov@zovs-centos7 hello]$ rpm -q glibc glibc-headers gcc make
glibc-2.17-196.el7.x86_64
glibc-headers-2.17-196.el7.x86_64
gcc-4.8.5-16.el7.x86_64
make-3.82-23.el7.x86_64

Not sure if this helps or not.

if i follow the hello world example, there is no issue, although gcc still fails to make whole app like ffmpeg :

steps to repro the issue:

Code: Select all

wget http://ffmpeg.org/releases/ffmpeg-3.3.4.tar.bz2
tar -xvjf ffmpeg-3.3.4.tar.bz2
cd ffmpeg-3.3.4
./configure

Is this just ffmpeg?

The issue is with everything that i try to compile, gcc, pip packages, locust, etc,...

I used your "steps to reproduce" on my usual fully updated CentOS 7.4 build machine, and ffmpeg built just fine (with a few warnings).

Even though you have the normal CentOS C compiler installed, are you actually using it? What does which gcc show?
