This apparently applies to non-Apple clang only.
When passed any optimization level other than 0, clang took liberty and
re-organised arguments passed to `RCT2_CALL*`, even in presence of
attributes put in place to prevent that: optnone,noinline.
This change allows easier project setup. It was previously possible to
produce a clang optimized build by manually recompiling and relinking
addresses.c.o.
Provide your own breakpad and point cmake at it.
git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git
mkdir breakpad && cd breakpad
../depot_tools/fetch breakpad # edit the script to use python2
cd src
LDFLAGS="-m32" CXXFLAGS="-m32" CFLAGS="-m32" CPPFLAGS="-m32" ./configure
LDFLAGS="-m32" CXXFLAGS="-m32" CFLAGS="-m32" CPPFLAGS="-m32" make -j 8
Run cmake on openrct2:
cd openrct2
vim CMakeLists.txt # provide your path to breakpad
mkdir build && cd build
cmake ../ -DWITH_BREAKPAD=ON
make -j 8
./openrct2 # open a game, select "about openrct2", crash
This doesn't really affect compilation in any way, but allows
CMake-based project generators to include the header files as well.
Previously headers without accompanying source files (like version.h)
were skipped when generating project files.
This enables compilation with `-DSTATIC=ON` for native Linux builds.
Do note that Linux systems rarely come with static libraries, so it may
not be a popular option.
This makes sure that shared library built with MinGW toolchain is linked
statically to *all* its dependencies, including libc, libstdc++, libsdl2
and all the others. This allows producing of working `openrct2.dll` by
cross-compiling.
I hit a bug with libcrypto, a dependency of libssl, which in turn is a
dependency of curl, which creates a `DllMain` entrypoint for static lib
too, but since we don't do anything in ours, this should be safe.
I have only had chance to try it out when cross-compiling, ideally it
should be tested under Cygwin/MSYS too, but it is too bothersome to
setup for me.
This enables install and package targets for make.
You can specify installation prefix with -DCMAKE_INSTALL_PREFIX=path,
when doing `make install`, OpenRCT shall be found there.
You can also use `make package` for creating packaged release files.
Fixed some CMakeLists.txt problems, made another target for converting
section images into something palatable by ld, modified the linker
script to place these ssection at predefined VMAs and updated openrct2.c
with new checks.
Mach-O defaults to having .text segment starting at 0x1000 RVA, which
clashes with the address space required for mmap to work properly.
This change tells linker to move the segment outside of required AS, and
then some, so that mmap can properly allocate required addresses without
evicting anything else.
Conditionally restore old functionality which got broken for mingw
builds with commit c93c1c7. Allow building with old version of code, but
generate a warning when doing so.
This is mostly refactoring of cmake scripts, but also touches build.sh
and install.sh. The cmake should be much more palatable now for major
Linux distributions.
At the same time, new configuration is introduced to Linux version, one
with Twitch enabled.
Please note, however, this change requires update of orctlibs.zip for
mingw builds.
