* m4: Merge our local change for threadlib.m4.NIIBE Yutaka2021-08-061-9/+16
| | | | | | | | | * m4/threadlib.m4: Add THREADLIB_CPPFLAGS support. -- GnuPG-bug-id: 5547 Signed-off-by: NIIBE Yutaka <[email protected]>
* m4: Update m4/threadlib.m4 from gnulib.NIIBE Yutaka2021-08-061-164/+469
| | | | | | | | | | | | | | | | | | | | | | | * m4/threadlib.m4: Update. -- Copied from gnulib commit of 12b5b00f93, so that we can support build with GNU C library 2.34 or later. Parts of our local changes are not needed any more: - Fix comment for "http" to "https" - Update to AS_HELP_STRING for newer autoconf One of our local change is canceled by this commit: - CPPFLAGS handling by THREADLIB_CPPFLAGS And it will be merged by following commit.

* Make multi-threading flags available via gpg-error-config.Werner Koch2014-01-241-6/+14
| | | | | | | | | | | | | | | | | * m4/threadlib.m4: Set THREADLIB_CPPFLAGS. * src/gpg-error-config.in: Add option --mt. * configure.ac: Add support for the --mt option. * src/gpg-error.m4: Add ac_subst GPG_ERROR_MT_CFLAGS and GPG_ERROR_MT_LIBS. -- Although, libgpg-error does not yet provide an API for multi-thread support, it is useful to add the already available detection to the config script. This allows the latest Libgcrypt to take advantage of this in its regression tests. In particular for the regression tests a gpgrt_thread functions would be useful and eventually added to libgpg-error. The new gpg-error.m4 script should already be used by other packages to be prepared for future updates.

Having them in a library named libgpg-error is a misnomer but this way we can achieve a smooth upgrade path. In contrasts to other GnuPG libraries, the gpgrt_ functions return a simple gpg_err_code_t and not gpg_error_t. The rationale for this is that a source of error identifier does not make sense here; it is better to use the source of error identifier of the caller. This can easily be achieved in a component by wrapping these function in a gpg_error macro/inline. There is no cross-compiling support for Posix platforms; the gen-posix-lock-obj tool must be run on the target system. Note that the gen-w32-lock-obj tool is not needed at build time but was used to figure out ABI definitions for Windows. Signed-off-by: Werner Koch <[email protected]>
