Currently there is a problem building packages that use *-config
scripts (for example gnupg), we are creating a
/bin/sh->/data/data/com.termux/files/usr/bin/sh symlink so that the
shebang for the scripts can be interpreted, but after
ecd214881a ("build-package: add new arg -c for "continue build"") the
symlink was deleted in termux_step_get_dependencies.
Name a patch *.patch.ondevice for it to only be applied when building
on device.
This can be useful if for example a tool for building documentation is
missing on device, or if a tool needed during build (but not runtime)
uses something that triggers selinux, fdsan or some other android
security thing.
When adding this, we go from compiling with
/home/builder/.termux-build/_cache/android-r21d-api-24-v4/bin/clang++ [...] -mrelocation-model pic -pic-level 2 -pic-is-pie [...]
to
/home/builder/.termux-build/_cache/android-r21d-api-24-v5/bin/clang++ [...] -mrelocation-model pic -pic-level 2 [...]
Before, we got a warning when compiling libandroid-spawn:
/home/builder/.termux-build/_cache/android-r21d-api-24-v4/bin/../lib/gcc/i686-linux-android/4.9.x/../../../../i686-linux-android/bin/ld: warning: shared library text segment is not shareable
and trying to use a program linked against libandroid-spawn gave an
error, see
https://github.com/termux/termux-packages/issues/7215#issuecomment-906154438
the Without this, libraries might end up with text relocations. For
some reason it does not seem to be an issue on the other arches.
%ci:no-build
This has already been done in termux_step_setup_build_folders. Doing
it here causes problems, after
ecd214881a
as BUILDDIR now might be SRCDIR, which should
not be created as it breaks zip extraction.
As replacement for TERMUX_PKG_QUICK_REBUILD. Running
./build-package.sh -c <package> starts a build for <package>, but does
not extract and patch the source from scratch. Instead it sets up the
build variables and starts from termux_step_make.
When working on a big package that can take hours to build it is
convenient to be able to build until there is an error, then apply
some new patch (manually) to the source, and then continue from where
the build failed.
All, or at least most, of our debs contain "./" as a folder. This
causes problems when extracting on some systems, as ./ then is the
system root directory /, and tar cannot change the permissions of this
folder. Trying to build on arch for example gives:
tar: .: Cannot change mode to rwxr-xr-x: Operation not permitted
tar: Exiting with failure status due to previous errors
The issue appeared on arch somewhat recently, maybe with tar 1.33. To
avoid having to rebuild all packages we now handle both data.tar.xz
types, with prefixed ./, and without.
Also remove some indentation levels while we are at it.
This avoids "./" being part of the tar. "./" translates to the
systemroot / when we extract, and this is problematic since tar cannot
change permissions and ownerships of this folder. tar 1.34 gives an
error:
tar: .: Cannot change mode to rwxr-xr-x: Operation not permitted
tar: Exiting with failure status due to previous errors
when we try to extract the data.tar.xz.
Do not fail immediately if signature is bad. This often happens when metadata
has been downloaded during repository update. Usually signature becomes fixed
in a few seconds, so we can rather wait than abort build immediately.
