The locale data in the recipe is generated using cpp, which results in differing amounts of whitespace depending on what compiler is used. This means that the files may differ in just whitespace, which is sufficient for RPM's multilib code to consider them different and not allow lib32-libx11-locale and lib64-libx11-locale to be installed at the same time.

Subject: [PATCH libX11] cpprules.in: squash whitespace in generated files
|
|
|
|
CPP is used to generate files, but as cpp reads files from the build host the
|
|
output has a number of blank lines at the beginning which varies depending on
|
|
what GCC and friends is used.
|
|
|
|
Pathalogical example:
|
|
|
|
$ cpp -undef -traditional /dev/null
|
|
# 1 "/dev/null"
|
|
# 1 "<built-in>"
|
|
# 1 "<command-line>"
|
|
# 31 "<command-line>"
|
|
# 1 "/usr/include/stdc-predef.h" 1 3 4
|
|
|
|
# 17 "/usr/include/stdc-predef.h" 3 4
|
|
|
|
[ 40 blank line ]
|
|
|
|
# 32 "<command-line>" 2
|
|
# 1 "/dev/null"
|
|
|
|
So depending on the content of stdc-predef.h and what other headers CPP will
|
|
load, the amount of whitespace in the generates files varies. This can result in
|
|
differences in reproducible environments, and file conflicts in multilib
|
|
environments.
|
|
|
|
As whitespace is irrelevant to these machine-readable files, extend the sed to
|
|
just delete blank lines.
