* projects: Delete the definition of _WINDOWS from the VStudio projectCosmin Truta2022-09-142-19/+19
| | | | | The _WINDOWS macro should not be defined on a modern Windows platform. This macro was predefined by 16-bit Windows compilers only.
* Delete vestigial declarations formerly used on 16-bit platformsCosmin Truta2022-09-143-23/+8
| | | | | | | | | Delete the structure members used in the 16-bit Turbo C memory models. Delete the PNG_ABORT declaration used in the 16-bit Windows build. Stop checking macros (e.g. _WINDOWS) predefined by 16-bit Windows compilers (but do check the __NT__ macro, which was the only one predefined by ancient Windows NT compilers).
* arm: Do not allow PNG_ARM_NEON_CHECK_SUPPORTED on ARM64Cosmin Truta2022-09-141-14/+14
| | | | | | | | | | ARM Neon is expected to be unconditionally available on ARM64. Issue an #error if PNG_ARM_NEON_CHECK_SUPPORTED is defined on an ARM64-based platform. For the plain ARM platforms where ARM Neon checking is not yet implemented, issue a slightly more descriptive #error, including a suggested course of action.
* arm: Avoid compiler warnings in palette_neon_intrinsics.cCosmin Truta2022-09-141-3/+5
| | | | Use correct int types; wrap PNG_UNUSED around unused arguments.
* Avoid -Wundef for MIPS and PPC symbols tooVadim Zeitlin2022-09-141-0/+4
| | | | | | | This is similar to d532334ef (Avoid -Wundef warnings when building libpng, 2017-11-13), but for the similar symbols used under the other architectures: always define them, even if just as 0, to avoid gcc warnings when comparing them with 0 later.
* Avoid -Wundef warnings for PNG_ARM_NEON_IMPLEMENTATIONVadim Zeitlin2022-09-141-0/+2
| | | | | | | | | | | Define this symbol as 0 instead of leaving it undefined when not using ARM NEON optimizations. No real changes, but just avoid a bunch of "PNG_ARM_NEON_IMPLEMENTATION" is not defined, evaluates to 0 [-Wundef] warnings when building the library.
* Fix a memory leak in png_set_tRNSSami Boukortt2022-09-132-1/+5
| | | | | | | | | | | | | | | This leak was discovered by OSS-Fuzz. The old structure of the code was along the lines of: allocate trans_alpha; if (problem) { // Jumps away from this function png_warning("tRNS chunk has out-of-range samples for bit_depth"); } mark trans_alpha as to-free; Signed-off-by: Cosmin Truta <ctruta@gmail.com>
* Fix a crash in png_convert_from_time_t with an invalid time_t argumentCosmin Truta2022-09-131-1/+11
| | | | | | | | | | | | | This bug was found by FUTAG, a program for generating automated fuzz-targets of libraries. TODO: Implement a safe function, alternative to png_convert_from_time_t, which takes a png_ptr argument and raises a png_error if the time_t argument is invalid.

* Fix private macro png_constcast; delete private type png_ptruintCosmin Truta2022-09-131-11/+2
| | | | | | | | In order to appease the compiler warnings that might affect the uses of png_constcast, it should be sufficient to cast the source pointer type to (const void*), and then to (void*), and then to the destination pointer type. An intermediate cast through an integer type, such as (png_ptruint), should not be needed.

* cmake: Fix the build on Unix with source files checked out on WindowsChristopher Sean Morrison2022-09-102-4/+20
| | | | | | | | | | | | | | | | | | The issue is that, by default, Git for Windows checks out text files with CRLF line endings. This is a problem for awk, which is expecting Unix-style LF line endings. When cloning on Windows and attempting to compile on WSL, Mingw or Cygwin, there may be an error from awk. The fix is to leverage CMake's ability to configure a file and perform EOL conversions. We copy the awk scripts from the source directory to the build directory. This portable method ensures they have LF endings, and the build logic is updated to use the build directory version. Intentionally avoiding .gitattributes to avoid setting precedent.

* cmake: Rename the target "symbol-check" to "scripts_symbols_chk"Cosmin Truta2022-09-101-2/+2

* cmake: Correctly handle generated filesGleb Mazovetskiy2022-09-101-32/+49
| | | | | | | | | | | | | | | | | | | Generated files depend on other generated files, and this previously resulted in the same custom command output being a dependency of multiple other custom commands without a shared custom targets. Adds a top-level target for each generated file and ensures that commands that depend on generated files also depend on the corresponding custom targets. Per CMake documentation: > Do not list the output in more than one independent target > that may build in parallel or the two instances of the rule > may conflict (instead use add_custom_target to drive the command > and make the other targets depend on that one).

* ci: Fix the Visual Studio verification on AppVeyor CICosmin Truta2020-12-311-5/+14
| | | | | | | | | | | | | | | | | | The Unix paths in Bash do not mix well with the Windows paths in CMake. The uppercase and the lowercase environment variables do not mix well in MSBuild. Et cetera. On AppVeyor CI, verification of Windows builds with the Visual Studio toolchain used to work, perhaps due to one or more lucky coincidences, but it stopped working after an upgrade on the AppVeyor CI site. Update ci_cmake.sh as follows: * Use POSIX commands like "mkdir" and "rm" instead of CMake commands like "make_directory" and "remove_directory". * Avoid using absolute paths in the CMake command line; use relative paths that are accessible from both Bash and Windows. * Clean up incidental mixtures of Windows and Bash-on-Windows environment variables like {$TEMP,$Temp,$temp} and {$TMP,$Tmp,$tmp}.
