https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D224107 Bug ID: 224107 Summary: multimedia/libvpx: broken on armv*, add an armv6-linux-gcc target Product: Ports & Packages Version: Latest Hardware: arm OS: Any Status: New Severity: Affects Many People Priority: --- Component: Individual Port(s) Assignee: jbeich@FreeBSD.org Reporter: mikael.urankar@gmail.com CC: freebsd-arm@FreeBSD.org Flags: maintainer-feedback?(jbeich@FreeBSD.org) CC: freebsd-arm@FreeBSD.org Assignee: jbeich@FreeBSD.org Created attachment 188541 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D188541&action= =3Dedit patch * the following condition is not correct, we can specify -mcpu=3Dcortex-a7 = to build for armv7: if ${CFLAGS:M-march=3Darmv7*} * I would like to add an armv6-linux-gcc target so we can benefit the arm_cpudetect feature on armv6 * 2 problems (an error and a warning) in patch-vpx__ports_arm__cpudetect.c: When we have the sys/auxv.h header we miss the getauxval function (sys/auxv= .h doesn't provide it) #if __has_include(<sys/auxv.h>) #include <sys/auxv.h> #else snip int arm_cpu_caps(void) { snip hwcaps =3D getauxval(AT_HWCAP); snip so the build fails: vpx_ports/arm_cpudetect.c.o: In function `arm_cpu_caps': vpx_ports/arm_cpudetect.c:(.text+0x50): undefined reference to `getauxval' the 2nd problem is that we don't provide the prototype for getauxval: cc -O -pipe -fno-strict-aliasing -march=3Darmv6 -DNDEBUG -O3 -fPIC -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=3D0 -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=3D64 -Wall -Wdeclaration-after-statement -Wdisabled-optimization -W float-conversion -Wpointer-arith -Wtype-limits -Wcast-qual -Wvla -Wimplicit-function-declaration -Wuninitialized -Wunused -Wextra -Wundef -Wshorten-64-to-32 -I. -I"/usr/ports/multimedia/libvpx/work/libvpx-1.6.1 " -c -o vpx_ports/arm_cpudetect.c.o vpx_ports/arm_cpudetect.c=20=20=20=20= =20=20=20=20=20=20=20=20=20=20=20=20=20=20=20 vpx_ports/arm_cpudetect.c:198:12: warning: implicit declaration of function 'getauxval' is invalid in C99 [-Wimplicit-function-declaration]=20=20=20=20= =20=20=20=20=20=20=20=20=20=20=20=20=20 hwcaps =3D getauxval(AT_HWCAP); The attached patch addresses the first 2 points, I don't know the code well enough to fix the others problems. --=20 You are receiving this mail because: You are the assignee for the bug.=
