These configure vars are modified in a curl-specific way and modified by
the configure process, but are never loaded from cache, even though they
are designated as _cv_. We should implement proper AC_CACHE_CHECKs for
them eventually.
|
|
This was automated by:
sed -b -i -f <(ack -A1 AC_CACHE_CHECK | \
ack -o 'ac_cv_.*?\b' | \
sort -u | xargs -n1 bash -c \
'echo "s/$0/curl_cv_${0#ac_cv_}/g"') \
$(git ls-files)
This only changed the prefix for 16 variables actually checked with
AC_CACHE_CHECK.

This patch is adopted from the MINGW-packages project. It makes it
possible to build curl both shared and static again.

... for CURL_CHECK_OPTION_RT
Closes #456
|
|
This option disables any attempts in configure to create dependency on
stuff requiring linking to librt.so and libpthread.so, in this case this
means clock_gettime(CLOCK_MONOTONIC, &mt).
We were in need to build curl which doesn't link libpthread.so to avoid
the following bug:

Poll has long been broken on Mac OS X. Starting with 10.9 (darwin13) it
now works correctly so this patch enables it there.

The latest version(s) of the icc compiler no longer accept the extra
space in the -we (warning enable), -wd (warning disable), etc.

The compiler test used a variable before it was assigned when it tried
to see how it acts on a mismatching prototype, which could cause a false
positive.
|
|
Use XC_CHECK_BUILD_FLAGS instead XC_CHECK_USER_FLAGS.

Instead of claiming it is an error, we call it a "note" to reduce the
severity level. But the following text now says the [variable] "*should*
only be used to specify"... instead of previously having said "may".

This function was only used twice, both in places where performance
isn't crucial (socks + if2ip). Removing the use of this function removes
the need to have our private version for systems without it == reduced
amount of code.
Also, in the SOCKS case it is clearly better to fail gracefully rather
than to truncate the results.
This work was triggered by a bug report on the strcal prototype in
strequal.h.
strlcat was added in commit db70cd28 in February 2001!

- Stabilization results in 4 public interface m4 macros:

XC_CONFIGURE_PREAMBLE_VER_MAJOR
XC_CONFIGURE_PREAMBLE_VER_MINOR
XC_CHECK_PATH_SEPARATOR
- Avoid one level of internal indirection
- Update comments
- Drop XC_OVR_ZZ40 macro

This avoids witness message in output when running configure --help,
while sending the message to config.log for other configure runs.

m4 quadrigraph shell comment technique allows proper autoconf
parentheses balancing in shell 'case' statements. The presence
of unbalanced parentheses may otherwise trigger expansion bugs.

- Faster path separator check
- Fix missing 'test' command

Some basic checks we make were placed early enough in generated
configure script when using autoconf 2.5X versions. Newer autoconf
versions expand these checks much further into the configure script,
rendering them useless. Using XC_CONFIGURE_PREAMBLE fixes placement
of early intended checks across all our autoconf supported versions.

Notes:
When running a configure script that has nested packages (for example
libcurl's configure with --enable-ares and c-ares sources embedded in
curl tree) and AC_CONFIG_SUBDIRS([nested-subdir]) machinery is used to
automatically run the nested configure script from within the parent
configure script, it happens that the nested _shell_ script will
inherit shell variables exported from the parent _shell_ script.
If for example parent configure script sets and exports LDFLAGS and LIBS
variables with proper values in order to link either a parent library or
program with a library which will be configured and built by a nested
package; It will happen that when the nested configure script runs, the
nested library does not exist yet and _any_ link-test done in the nested
configure will fail, such as those that autoconf macros perform in order
to detect existing compiler and its characteristics, the result is that
the nested configure script will fail with errors such as:
configure: error: C compiler cannot create executables
For now, we no longer export variables previously exported here.
On the other hand, AC_SUBST'ing them is appropriate and even with nested
packages each package's config.status gets its own package values.
So we reinstate AC_SUBST'ing previously AC_SUBST'ed variables.

This commit renames lib/setup.h to lib/curl_setup.h and
renames lib/setup_once.h to lib/curl_setup_once.h.
Removes the need and usage of a header inclusion guard foreign
to libcurl. [1]
Removes the need and presence of an alarming notice we carried
in old setup_once.h [2]
----------------------------------------
1 - lib/setup_once.h used __SETUP_ONCE_H macro as header inclusion guard
up to commit ec691ca3 which changed this to HEADER_CURL_SETUP_ONCE_H,
this single inclusion guard is enough to ensure that inclusion of
lib/setup_once.h done from lib/setup.h is only done once.
Additionally lib/setup.h has always used __SETUP_ONCE_H macro to
protect inclusion of setup_once.h even after commit ec691ca3, this
was to avoid a circular header inclusion triggered when building a
c-ares enabled version with c-ares sources available which also has
a setup_once.h header. Commit ec691ca3 exposes the real nature of
__SETUP_ONCE_H usage in lib/setup.h, it is a header inclusion guard
foreign to libcurl belonging to c-ares's setup_once.h
The renaming this commit does, fixes the circular header inclusion,
and as such removes the need and usage of a header inclusion guard
foreign to libcurl. Macro __SETUP_ONCE_H no longer used in libcurl.
2 - Due to the circular interdependency of old lib/setup_once.h and the
c-ares setup_once.h header, old file lib/setup_once.h has carried
back from 2006 up to now days an alarming and prominent notice about
the need of keeping libcurl's and c-ares's setup_once.h in sync.
Given that this commit fixes the circular interdependency, the need
and presence of mentioned notice is removed.
All mentioned interdependencies come back from now old days when
the c-ares project lived inside a curl subdirectory. This commit
removes last traces of such fact.

Provide a 'traceable' AC_CONFIG_MACRO_DIR definition only when using
an autoconf version that does not provide it, instead of what we were
doing up to now of providing and overriding AC_CONFIG_MACRO_DIR for
all autoconf versions.

76 private header files renamed to use our standard naming scheme.
This change affects 322 files in libcurl's source tree.
