* cross-emerge: Default to using no prefixbug_642604James Le Cuirot2019-07-091-7/+8
| | | | | | | | | | | | | | | | | | | | | | On non-prefixed systems, cross-emerge installs to /usr/${CHOST} by default. On prefixed systems, this default effectively becomes ${BROOT}/usr/${CHOST}/${BROOT}, which is unexpected and makes little sense. The first BROOT originates from the ROOT setting in the cross make.conf. The second BROOT is the prefix that Portage is configured to use by default. We therefore need to avoid the second BROOT by overriding Portage with a blank EPREFIX value. Note that a bug in Portage itself means that this is ineffective on versions before 2.3.69 but it's no worse than it was before either. For users who do want to set their own EPREFIX, the PORTAGE_CONFIGROOT default has been updated to ${SYSROOT}${EPREFIX} as the prefixed location is required for this variable. This is despite man emerge suggesting otherwise! Closes: https://bugs.gentoo.org/642604 Signed-off-by: James Le Cuirot <chewi@gentoo.org>

* crossdev: don't enable USE=pie by default on any bare-metal targetsSergei Trofimovich2018-09-181-6/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | Unfortunately embedded world has a long way to go to adopt --enable-default-pie as a first class citizen. Note: --enable-default-pie enabled two things: - PIC-friendly code generation (-fPIE) - PIE executables (-pie) Normally one would expect firmware to pass compiler modes explicitly to gcc: -fPIC (or -mauto-pic, -fno-PIC), -ffreestanding, -nostdlib. Unfortunately upstreams are frequently reluctant to explicitly specify new moving parts available in gcc (in this case -no-pie) and expect gcc to behave as it used to in the world before --enable-default-pie. Unfortunate but not entirely unreasonable. Disable --enable-default-pie until user explicitly requests USE=pie.

* wrappers: prevent use of wine to convert between path typesMarty E. Plummer2018-07-312-0/+3
| | | | | | | | | | | | libtool.m4 uses lt_cv_to_host_file_cmd to store the name of a function used to convert between unix and win32 path styles; when doing a linux to mingw cross-compilation it ends up with func_convert_file_nix_to_w32 which uses the winepath utility to do the job. However, using that tool will create a wineprefix in ${CATEGORY}/${P}/homedir and potentially cause access violations in sandbox.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Copying note as-is here: ``` Create directories usually created by sys-apps/baselayout Why we do that at all: For multilib-aware targets (ppc64, s390x, sparc64, x86_64) Gentoo normally uses libdir=lib64. For crossdev it means /lib and /usr/lib does not get created at all but gcc relies on their presence by refering to =/lib64 as =/usr/lib/../lib64 when builds itself (see https://bugs.gentoo.org/652724) Thus we create non-symlinked layout early. ``` Before the change 'crossdev -t powerpc64le-foo-linux-gnu' failed at gcc-stage2 as: ``` ... \ -shared -nodefaultlibs -Wl,--soname=libgcc_s.so.1 \ -o ./libgcc_s.so.1.tmp \ ... \ /usr/libexec/gcc/powerpc64le-foo-linux-gnu/ld: cannot find crti.o: No such file or directory access("/usr/powerpc64le-foo-linux-gnu/usr/lib/../lib64/crti.o", R_OK) = -1 ENOENT (No such file or directory) ``` The change adds empty directory '/usr/powerpc64le-foo-linux-gnu/usr/lib' to make ld probing finally find 'crti.o' in $SYSROOT.
