Bug ID: 79147
Summary: Uselsss _GLIBCXX_PACKAGE_* macros in
<bits/c++config.h>
Product: gcc
Version: 6.3.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: redi at gcc dot gnu.org
Target Milestone: ---
The libstdc++ headers define these macros:
/* Define to the address where bug reports for this package should be sent. */
#define _GLIBCXX_PACKAGE_BUGREPORT ""
/* Define to the full name of this package. */
#define _GLIBCXX_PACKAGE_NAME "package-unused"
/* Define to the full name and version of this package. */
#define _GLIBCXX_PACKAGE_STRING "package-unused version-unused"
/* Define to the one symbol short name of this package. */
#define _GLIBCXX_PACKAGE_TARNAME "libstdc++"
/* Define to the version of this package. */
#define _GLIBCXX_PACKAGE__GLIBCXX_VERSION "version-unused"
These are all pretty useless, but the last one is particularly silly. It should
probably by _GLIBCXX_PACKAGE_VERSION, but the sed rule in include/Makefile.am
modifies it twice:
sed -e 's/HAVE_/_GLIBCXX_HAVE_/g' \
-e 's/PACKAGE/_GLIBCXX_PACKAGE/g' \
-e 's/VERSION/_GLIBCXX_VERSION/g' \
-e 's/WORDS_/_GLIBCXX_WORDS_/g' \
-e 's/ICONV_CONST/_GLIBCXX_ICONV_CONST/g' \
-e '/[ ]_GLIBCXX_LONG_DOUBLE_COMPAT[ ]/d' \
< ${CONFIG_HEADER} >> $@ ;\
If we did s/PACKAGE_/_GLIBCXX_PACKAGE_/ instead then it would give a more
sensible result.
We should also consider replacing this whole thing with something based on
AX_PREFIX_CONFIG_H instead, so everything in the auto-generated config.h gets
