We currently unconditionally enable the "-Wall" and "-Wextra" flags.
Some platforms rely on compilers which do not support these flags,
though. One of these platforms is Haiku, which does not support
"-Wextra" due to being stuck on GCC version 2.
Fix builds on such platforms by adding these flags only if supported by
the compiler.
`xlocale.h` only defines `regcomp_l` if `regex.h` was included as well.
Also change the test cases to actually test `p_regcomp` works with
a multibyte locale.
The `PKG_CHECK_MODULES` function searches a pkg-config module and
then proceeds to set various variables containing information on
how to link to the library. In contrast to the `FIND_PACKAGE`
function, the library path set by `PKG_CHECK_MODULES` will not
necessarily contain linking instructions with a complete path to
the library, though. So when a library is not installed in a
standard location, the linker might later fail due to being
unable to locate it.
While we already honor this when configuring libssh2 by adding
`LIBSSH2_LIBRARY_DIRS` to the link directories, we fail to do so
for libcurl, preventing us to build libgit2 on e.g. FreeBSD. Fix
the issue by adding the curl library directory to the linker
search path.
The MSYS2 build system automatically compiles all code with position-independent
code. When we manually add the -fPIC flag to the compiler flags, MSYS2 will
loudly complain about PIC being the default and thus not required.
Fix the annoyance by stripping -fPIC in MSYS2 enviroments like it is already
done for MinGW.
This is useful to force "smart" IDEs (like CLIon) to use debug
flag -g even it may have decided that "-D_DEBUG" (which is
already present) is sufficient.
Android NDK does not have a `struct timespec` in its `struct stat`
for nanosecond support, instead it has a single nanosecond member inside
the struct stat itself. We will use that and use a macro to expand to
the `st_mtim` / `st_mtimespec` definition on other systems (much like
the existing `st_mtime` backcompat definition).
The MSVC_SPLIT_SOURCES function is helpful for other IDEs, like Xcode,
and will split the source files up into their target directories,
instead of merely placing them all in a "Sources" directory.
Rename MSVC_SPLIT_SOURCES to IDE_SPLIT_SOURCES and enable it for Xcode.
This allows us to remove OS checks from source code, instead relying
on CMake to detect whether or not `struct stat` has the nanoseconds
members we rely on.
Before:
libdir=/usr//usr/lib64
includedir=/usr//usr/include
After:
libdir=/usr/lib64
includedir=/usr/include
(note the duplication of /usr in the before case)
The embedding was removed as a libssh2 release with Windows crypto
support became available, but dependencies are still annoying so this
ahs been requested again.
This reverts commit 20dcb7315c.
Starting at OS X 10.8, the Security framework offers some functions
which are unified across OS X and iOS. These are the functions that we
use.
Older versions of OS X do not have these functions and we fail to
compile. In these situations, fall back to using OpenSSL for our TLS
stream instead.
These are treated as a list by CMake itself, which means that treating
them as a simple string can put semicolons in our ld command-line if we
have libraries which are not installed on the standard locations.
Treat the variable as a CMake list and replace it with the space-delimited
list just before writing it out to our pc file.
