Despite the comment, only -fPIE was enabled by default in the Clang
toolchain, and not -fPIC. With the LLVM 14 upgrade, we made PIC the
default.

Backports an upstream fix for a bug that caused the host compiler to be
used for linking even though the cross-compiler was specified in the
`CC` environment variable.
This didn't cause an issue for SERENITY_ARCH=i686 on Linux hosts,
because seeing that the host linker couldn't deal with i686 objects, the
configure script fell back to generating only a static library. On
x86-64, the host toolchain was able to deal with the object files, but
tried to link those to host libraries. On macOS hosts, nothing worked.

Even though Clang generates PIC objects by default, an R_386_PC32
relocation still slips into libz.a if we don't set -fPIC explicitly.

We may need entries with spaces in makeopts, installopts, and
configopts, and at that point we should also convert depends and
auth_opts to avoid confusion.
|
|
By setting `--uname=Linux`, we tell `configure` to use the right tools
for cross compilation. Without this on e.g. macOS it would try to use
XCode's `libtool` which would then fail.

Without a SONAME gcc will put the whole library path into executables
which link against these libraries:
$ readelf -d Root/usr/local/games/openttd
Dynamic section at offset 0xf0747c contains 32 entries:
Tag Type Name/Value
0x00000001 (NEEDED) [libgcc_s.so]
0x00000001 (NEEDED) [/serenity/Build/i686/Root/usr/local/lib/libpng.so]
0x00000001 (NEEDED) [/serenity/Build/i686/Root/usr/local/lib/libz.so]
0x00000001 (NEEDED) [/serenity/Build/i686/Root/usr/local/lib/liblzma.so]
0x00000001 (NEEDED) [libSDL2-2.0.so.1]
0x00000001 (NEEDED) [libicui18n.so.69]
0x00000001 (NEEDED) [libicuuc.so.69]
0x00000001 (NEEDED) [libicudata.so.69]
0x00000001 (NEEDED) [libpthread.so]
0x00000001 (NEEDED) [libm.so]
0x00000001 (NEEDED) [libc.so]
This causes the executable to fail because the dynamic linker
tries to find the library in the incorrect path.

- Replaced /Root with
- Improved documentation.
- Removed a few typos.
- Replaced with
- Added brackets in some cases.
Most of the changes were reviewed and applied manually.

This manually builds shared libraries for a bunch of ports. Using
libtool would be preferable but that's currently broken so I'm
linking the shared libraries manually.

* Use ${version} instead of explicit version numbers in urls/filenames
* Move -L option to port script, as this is always good
* Fix some various other stuff
|
|
We only support static linking at the moment, and zlib was trying to
build itself as a shared library.
Fixes #1135.

Partial revert of 704f48d7f3a1a88047a64b4e2939878d6d4fafb8.
These changes made the ports system unusable.
|
|
Ports/.port_include.sh, Toolchain/BuildIt.sh, Toolchain/UseIt.sh
have been left largely untouched due to use of Bash-exclusive
functions and variables such as $BASH_SOURCE, pushd and popd.
