2008-01-05michael_d writes in 1879:Mike Frysinger
When no TIOCGPTN definition is present in the kernel headers, the library's ptsname() function will not work. The libc/stdlib/ptsname_r.c file is the problem. This file includes a complicated nest of #if directives. One of these #if's has the opposite sense from what is required.

2008-01-05michael_d writes in #1874: Mike Frysinger
On an i386 platform with no rt_sigsuspend syscall (ie: Linux 2.0), compilation will halt on libc/sysdeps/linux/common/sigsuspend.os with a cryptic error message: "Error: non-constant expression in ".if" statement" I've investigated and found that the cause is that a literal '0' is being passed into a block of complex assembler macrology that is only prepared to deal with register names - '%eax', etc. In turn, that seems to be because of a typo in the GCC register constraints. The constraints for 2 and 3-argument syscalls includes a "C" constraint. To gcc, "C" means an SSE floating point constant -- an unlikely element in a syscall. I suspect the author meant to type "S" (%esi).

2007-12-03realpath: reduce stack usage from 3*PATH_MAX (12k) to 1*PATH_MAX (4k).Denis Vlasenko
reduction is achieved by direct use of user-supplied PATH_MAX sized buffer for result (without intermediate copy) and changes in copy_buf[] usage - now it is used for both "source" pathname and link name (it works because they have to be less than PATH_MAX combined, otherwise we return NULL).

Jean-Christian de Rivaz writes: The attached patch solve an issue I faced while using the libdbus-glib waiting for a D-Bus message or the end of a glib timer at the same time. This specific case of use generate a poll call with a zero timeout. On platformes with the glibc a zero timeout poll return immetiately even if there is no file descriptor event. But on platformes with uClibc a zero timeout poll block until a file descriptor event occurs.

- adjust setting flags accordingly to use (hardcoded, see below) -Wl, Potential improvements: *) --warn-unresolved-symbols should perhaps be used for all libs *) eventually rename LDFLAGS to CC_LDFLAGS *) probe for compiler driver's notion of flag to use for passing in linker flags (i.e. don't hardcode "-Wl,")

2007-09-28This patch will fix a problem when the same host is defined with both IPv4 andMike Frysinger
IPv6 entries in /etc/hosts. Previous only the first of these host would work, as uClibc would read the /etc/hosts file from top to bottom, failing if the first hit did not match the IP type. Now uClibc will continue reading, even if the first correct entry name, but wrong IP type fails. Thus, allowing a second correct entry name with correct IP type will result in a name resolve.

I got the library to compile with the attached patches, though dynamic loader crashes early. In buildroot I changed the architecture name by hand from sparc to sparc64, otherwise the compiler produced 32-bit files with V9 (64-bit) instructions. This configuration is not supported by QEMU, so I aimed for pure 64-bit. I think Sparc64 option needs to be added to buildroot. The _Qp_ ops seem to be required by the ABI. This and setjmp patches are just hacks to get the compilation further. The _Qp_ ops can be found in glibc, would it be OK to use those? V9 assembler requires declarations for global register use. The mem* functions in sparc32 directory did not work. They are actually used only by the hybrid 32-bit + V9 CPU configuration.
