| Summary | 0000317: buildroot for sh4 stops with "undefined reference to `__sigprocmask'" | ||||||||
| Description |
When trying to use buildroot for sh4, I cannot get past creating uClibc as I get this error: /export/sh4/buildroot/build_sh4/staging_dir/bin/sh4-linux-uclibc-ld -EL -shared --warn-common --warn-once -z combreloc -z defs -s -soname=libc.so.0 -o libuClibc-0.9.27.so \ --whole-archive shared_libc.a \ ../libc/misc/internals/interp.o --no-whole-archive \ -init __uClibc_init ../lib/ld-uClibc.so.0 /export/sh4/buildroot/build_sh4/staging_dir/lib/gcc/sh4-linux-uclibc/3.4.4/libgcc.a shared_libc.a(longjmp.o): In function `siglongjmp': longjmp.c:(.text+0x40): undefined reference to `__sigprocmask' make[2]: *** [shared] Error 1 |
||||||||
| Additional Information |
gcc-3.4.4 used as compiler and cross compiler. uClibc daily snapshot as of today. Linux header 2.4.29 (2.6.11 gives me another error about asm/ucb.h missing, but that's a completely different problem). When compiling for sh4 I also get some questions about CPU type and subtype. sh is not well supported it seems... The questions are trivial to answer though. However the missing sigprocmask is not (for me). In glibc, there's a file sigprocmask.c which is missing in uClibc. Maybe that's all which is needed. |

If I comment out the reference to __sigprocmask in longjmp.c, then I get another stop with __fpscr_values being undefined: /export/sh4/buildroot/build_sh4/staging_dir/bin/sh4-linux-uclibc-ld -EL -shared --warn-common --warn-once -z combreloc -z defs -s -soname=libm.so.0 \ -o libm-0.9.27.so --whole-archive libm.a \ --no-whole-archive ../libc/misc/internals/interp.o \ -L../lib -lc /export/sh4/buildroot/build_sh4/staging_dir/lib/gcc/sh4-linux-uclibc/3.4.4/libgcc.a libm.a(fpmacros.o): In function `__fpclassifyf': fpmacros.c:(.text+0x60): undefined reference to `__fpscr_values' make[2]: *** [shared] Error 1 It is defined in crt0.S though: #if defined __CONFIG_SH4__ .global __fpscr_values __fpscr_values: .long 0 .long 0x80000 #endif And __CONFIG_SH4__ is defined in include/bits/uClibc_config.h: #define __CONFIG_SH4__ 1 |

Ok, after having a hard look at __fpscr_values the problem with it was found to be: .global does not work just like .globl which does not work either. I'll post a bug report in the uClibc bug tracker The problem with `__sigprocmask' remains. |

this should be fixed in uClibc 0.9.28 |
