* configure.ac: New option --enable-ld-version-script. (GPGRT_USE_VISIBILITY): New ac_define. (HAVE_LD_VERSION_SCRIPT): New am_conditional. * src/gpg-error.vers: New. * src/gpgrt-int.h: New. * src/visibility.c, src/visibility.h: New. Lot of changes to symbold names. -- This is only doe for the old API. The estream API needs to be added.

Add gpgrt_lock_ functions.

* src/gpg-error.h.in (GPGRT_LOCK_DEFINE): New. (gpgrt_lock_init): New. (gpgrt_lock_lock): New. (gpgrt_lock_unlock): New. (gpgrt_lock_destroy): New. (gpgrt_yield): New. * src/gpg-error.def.in: Add new functions. * m4/lock.m4, m4/threadlib.m4: New. Taken from current gnulib. * configure.ac: Call gl_LOCK. Check size of pthread_mutex_t. Add LIBTHREAD to GPG_ERROR_CONFIG_LIBS. * src/err-codes.h.in (GPG_ERR_INV_LOCK_OBJ): New. * src/gen-posix-lock-obj.c: New. * src/gen-w32-lock-obj.c: New. * src/lock.h, src/thread.h: New. * src/posix-lock-obj.h, src/w32-lock-obj.h: New. * src/posix-lock.c, src/w32-lock.c: New. * src/posix-thread.c, src/w32-thread.c: * src/w32-lock-obj-pub.in: New. * src/mkheader.c (include_file): Support build time include files. (write_special): Add keyword "include:lock-obj". * src/Makefile.am: (posix-lock-obj-pub.in): New rule. (noinst_PROGRAMS): Add gen-*-lock-obj helpers. * tests/t-common.h: New. * tests/t-lock.c: New. * tests/Makefile.am (t_lock_LDADD): Add new test. -- This patch introduces the gpgrt_ functions which will be extended over time to provide a library of commonly used code in GnuPG and Libgcrypt. 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

Add version macros and check function.

2013-02-23T19:18:49Z

* configure.ac (VERSION_NUMBER): New ac_subst. (BUILD_FILEVERSION): Build on all platforms (BUILD_TIMESTAMP): Try to use an ISO string. * src/Makefile.am (extra-h.in): Add new version numbers. * src/versioninfo.rc.in: Update copyright year. * src/version.c: New. (gpg_error_check_version): New API. * src/gpg-error.h.in: Add gpg_error_check_version prototype. * src/gpg-error.def.in: Add gpg_error_check_version * tests/t-version.c: New. * tests/Makefile.am (TESTS): Add t-version.c * src/gpg-error-config.in: s/VERSION/PACKAGE_VERSION/. -- All other GnuPG libraries do this, thus we do it here as well.
