* hardening: add option for -fstack-clash-protectionMichael Olbrich2019-02-211-0/+1
| | | | Signed-off-by: Michael Olbrich <m.olbrich@pengutronix.de>
* ptxd_init_*_env: use -B instead of -LMichael Olbrich2018-11-171-1/+1
| | | | | | | | | | | It's not quite correct, but it shouldn't hurt and with -B the path is added to 'libraries:' in 'gcc -print-search-dirs'. Libtool uses this for manual seaching. This avoid explicit paths to .la files found in the system when building host packages. Also assume -print-search-dirs means compiling/linking to ensure the options are used.

* wrapper: try to make all debug paths relative to PTXDIST_WORKSPACEMichael Olbrich2018-10-034-0/+8
| | | | | | | | | | | The debug sections containing these paths are used to calculate the build-id, so building a BSP in a different directory will result in a different build-id even if nothing else changes. Avoid this by using -fdebug-prefix-map to make the paths relative. Also expand the gdb wrapper to handle this even if it is called from a different directory.

* wrapper: improve blacklist handlingMichael Olbrich2018-07-091-0/+5
| | | | | | | | | | | | Explicitly disable build-id if it is blacklisted. It may be enabled by default in the toolchain. Use TARGET_HARDEN_STACK to blacklist all stack protector options. Note: With 'dash', variables for a specific command remain set afterwards if the command is a shell function. Use '()' to make sure the existing value is not overwritten.

* wrapper: add rpath-link for some rpathsMichael Olbrich2018-04-181-0/+3
| | | | | | | | | | | | | | | With new versions of binutils, ld will prepend the sysroot to all absolute rpaths before using them at build time. This breaks rpaths for build directories. Specifically it breaks building the gobject-introspection helper programs. Fix this by adding the same path with -rpath-link. Note: This is incomplete: It only works for "-Wl,-rpath,<path>" but not for "-Wl,-rpath -Wl,<path>". It fixes all known issues in PTXdist so it is good enough for now.

* gdb-wrapper: add the nfsroot to the auto-load safe-pathMichael Olbrich2018-03-021-0/+1
| | | | | | | The only useable path for auto-load scripts is right next to the corresponding binary. Anything else is broken when working with a sysroot. Signed-off-by: Michael Olbrich <m.olbrich@pengutronix.de>
* wrapper: add -fno-diagnostics-show-caret when using iceccMichael Olbrich2018-02-281-0/+11
| | | | | | | Otherwise icecc may need to rebuild files locally. Especially qt4 seems to be affected by this. Signed-off-by: Michael Olbrich <m.olbrich@pengutronix.de>
* Debugging: add support for 'build-id'sJuergen Borleis2017-06-211-0/+7
| | | | | | | | | | | | | | | | | | | | Recent debugging tools support separate binaries and debug information files. Providing a unique 'build-id' embedded in the binary enables the debugging tools to select the correct and matching debug information files from the system's root filesystem. The 'build-id' is a 40 character calculated SHA1 from important sections in the binary. The debug information files get stored at a central direcory at "/usr/lib/debug/", with a special path based on the 'build-id'. If the 'build-id' is "123456789abcdef", the path and filename will be ".build-id/12/3456789abcdef.debug". Its possible to have more than one 'build-id' in the binary. This implementation prefers the first one in the list, which might be the wrong one. It's unclear yet how the common debugging tools will behave in this case.

* wrapper: add gdb wrapperMichael Olbrich2017-06-211-0/+11
| | | | | | Add arguments to set sysroot and debug-file-directory. Signed-off-by: Michael Olbrich <m.olbrich@pengutronix.de>
* wrapper: disable icecc in fakerootMichael Olbrich2017-04-111-0/+3
| | | | | | | | | | icecc creates temporary files with the username in the name. In fakeroot the username is 'root' so this can cause collisions in multi-user environments. Nothing is supposed to be compiled in fakeroot, but it can happen during 'make install' due to broken dependencies. Signed-off-by: Michael Olbrich <m.olbrich@pengutronix.de>
* wrapper: add PTXDIST_CROSS_CPPFLAGS lateMichael Olbrich2016-10-211-1/+1
| | | | | | | | | | | | These are only the -isystem arguments for sysroot. They should be added at the end of the commandline. This way any other -isystem generated by the package build system has priority. This fixes building Qt5 packages if Qt4 is installed as well. For Q55 qmake produces '-isystem <sysroot>/usr/include/qt5'. Without this the Qt4 headers in <sysroot>/usr/include are used. Signed-off-by: Michael Olbrich <m.olbrich@pengutronix.de>

* Fix (host) gcc wrapper on Gentoo LinuxBernhard Walle2013-03-221-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | On Gentoo, the host compiler can only be executed if basename(argv[0]) is 'gcc' (or 'g++' etc.), not if it's 'gcc.real'. Then it invokes gcc-config and fails: | % ln -s /usr/bin/gcc gcc.real | % ./gcc.real --version | | * gcc-config: Could not get portage CHOST! | * gcc-config: You should verify that CHOST is set in one of these places: | * gcc-config: - //etc/portage/make.conf | * gcc-config: - active environment | gcc-config: error: could not get compiler binary path: No such file or directory I'm not a Gentoo expert (I'm just forced to use it for that purpose ;-)), so I cannot explain further details. This patch makes ptxdist working on Gentoo by changing the symbolic link from <name>.real to real/<name>, i.e. moving the final toolchain symlink to some other directory, keeping the basename.
