This restores socket libs to their pre-regression positions.
Without this, `ld` doesn't find `ws2_32` symbols when referenced
from TLS libs.
Regression from 31fb8860db
- cmake: always link `ws2_32` on Windows. Also add it to `libssh2.pc`.
Fixes#745
- agent: fix gcc compiler warning:
`src/agent.c:296:35: warning: 'snprintf' output truncated before the last format character [-Wformat-truncation=]`
- autotools: fix `EVP_aes_128_ctr` detection with binutils `ld`
The prerequisite for a successful detection is setting
`LIBS=-lbcrypt` if the chosen openssl-compatible library requires
it, e.g. libressl, or quictls/openssl built with
`-DUSE_BCRYPTGENRANDOM`.
With llvm `lld`, detection works out of the box. With binutils `ld`,
it does not. The reason is `ld`s world-famous pickiness with lib
order.
To fix it, we pass all custom libs before and after the TLS libs.
This ugly hack makes `ld` happy and detection succeed.
- agent: fix Windows-specific warning:
`src/agent.c:318:10: warning: implicit conversion loses integer precision: 'LRESULT' (aka 'long long') to 'int' [-Wshorten-64-to-32]`
- src: fix llvm/clang compiler warning:
`src/libssh2_priv.h:987:28: warning: variadic macros are a C99 feature [-Wvariadic-macros]`
- src: support `inline` with `__GNUC__` (llvm/clang and gcc), fixing:
```
src/libssh2_priv.h:990:8: warning: extension used [-Wlanguage-extension-token]
static inline void
^
```
- blowfish: support `inline` keyword with MSVC.
Also switch to `__inline__` (from `__inline`) for `__GNUC__`:

- example/test: fix MSVC compiler warnings:
- `example\direct_tcpip.c(209): warning C4244: 'function': conversion from 'unsigned int' to 'u_short', possible loss of data`
- `tests\session_fixture.c(96): warning C4013: 'getcwd' undefined; assuming extern returning int`
- `tests\session_fixture.c(100): warning C4013: 'chdir' undefined; assuming extern returning int`
- delete unused macros:
- `HAVE_SOCKET`
- `HAVE_INET_ADDR`
- `NEED_LIB_NSL`
- `NEED_LIB_SOCKET`
- `HAVE_NTSTATUS_H`
- `HAVE_NTDEF_H`
- build: delete stale zlib/openssl version numbers from path defaults.
- cmake: convert tabs to spaces, add newline at EOFs.
Closes#811
Before this patch, the `snprintf()` fallback logic for envs not
supporting this function (i.e. Visual Studio 2013 and older) varied
depending on build tool, and used different techniques in examples,
tests and libssh2 itself.
This patch aims to apply a common logic to libssh2 and examples/tests.
- libssh2: use local `snprintf()` fallback with all build tools.
We already had a local implementation, but only with CMake. Move that
to the library as `_libssh2_snprintf()`, and map `snprintf()` to it
when `HAVE_SNPRINTF` is not set.
Also change the length type from `int` to `size_t`, and fix
formatting.
- set or detect `HAVE_SNPRINTF` in non-CMake builds.
Detect in autotools. Keep existing logic in `win32/libssh2_config.h`.
Always set for OS/400, NetWare and VMS, keeping existing behaviour.
(OS/400 builds use a different local implementation)
- examples/tests: drop the CMake-specific fallback logic and map
`snprintf()` to `_snprintf()` for old MSVC versions, like we did
before with other build tools. This is unsafe, but should be fine for
these uses.
- `win32/libssh2_config.h`: make it easier to read.
Closes#812
VS2015 moved stdio functions to the header files as inline function. That means check_function_exists can't detect them because it doesn't use header files - just does a link check. Instead we need to use check_symbol_exists with the correct headers.
