Summary: missing C standard headers
Product: Fedora Core
Version: devel
Platform: All
OS/Version: Linux
Status: NEW
Severity: normal
Priority: normal
Component: perl
AssignedTo: jvdias(a)redhat.com
ReportedBy: jvdias(a)redhat.com
QAContact: dkl(a)redhat.com
CC: fedora-perl-devel-list(a)redhat.com
Description of problem:
All perl versions on Linux / glibc / gcc systems fail to look for the
C standard header files in the correct location, eg. :
stddef.h syslimits.h stdarg.h float.h stdbool.h
These are gcc built-in headers, and cpp searches for them in the gcc
architecture specific include directory before the system include directory:
/usr/lib/gcc/${arch}-${os}/${gcc-version}/include
During the perl build, perl does not look for any headers in the
gcc architecture specific include directory, but instead either
fails to find the header at all, or finds versions of them used
only by the kernel, eg. as shown by this excerpt from a log of a
Rawhide perl build :
---
+ for i in asm/termios.h syscall.h syslimits.h syslog.h sys/ioctl.h sys/socket.h
sys/time.h wait.h ...
...
+ /var/tmp/perl-5.8.7-0.5.fc5-root-jvdias//usr/bin/perl
/var/tmp/perl-5.8.7-0.5.fc5-root-jvdias//usr/bin/h2ph -a -d
/var/tmp/perl-5.8.7-0.5.fc5-root-jvdias/usr/lib/perl5/5.8.7/i386-linux-thread-multi
syslimits.h
Can't open syslimits.h: No such file or directory
syslimits.h -> syslimits.ph
---
( empty syslimits.ph - no syslimits.ph shipped )
---
+ /var/tmp/perl-5.8.7-0.5.fc5-root-jvdias//usr/bin/perl
/var/tmp/perl-5.8.7-0.5.fc5-root-jvdias//usr/bin/h2ph -a -d
/var/tmp/perl-5.8.7-0.5.fc5-root-jvdias/usr/lib/perl5/5.8.7/i386-linux-thread-multi
asm/termios.h
...
linux/stddef.h -> linux/stddef.ph
---
No <stddef.h> shipped, only <linux/stddef.h>, which is meant to be used only
by the kernel.
This results in many system headers that reference the C standard headers
being unusable because the C standard headers are not found
(eg. sys/resource.ph -> bits/resource.ph -> linux/types.ph -> stddef.ph
-> stddef.ph not found,
bug 170088 ).
The perl build process should find the C standard headers in their correct
location, as many system perl headers that are shipped by perl reference them.
Version-Release number of selected component (if applicable):
ALL
How reproducible:
100%
Steps to Reproduce:
$ perl -e 'require "sys/resource.ph";'
Actual results:
Fails due to missing stddef.ph
Expected results:
No error
