# 03:38:41 Scraph Hey all, a quick `newb' question ... is my tool-chain directory, after the tool-chain has been built, simply intended to contain the literal binaries under bin ... or is this where I should be putting cross-platform includes/libraries as well?
# 03:40:12 Scraph I compiled a tool-chain and found that it cannot locate "omp.h", OpenMP, a fairly `standard' header ... so where should I be filling in these holes as I find them?
# 03:41:49 Scraph more clearly, the tool-chain itself compiles fine ... I find that I'm missing fairly standard headers when I go to use it...

# 19:14:05 bhundven dang weather keeps knocking out my internet
# 19:37:09 ius joins #crosstool-ng
# 19:39:46 ius are there any known issues building native gdb against uClibc 0.9.X for mipsel?
# 19:40:10 ius first it was attempting to link expat against /usr/lib/libexpat.so (ie. my host expat)
# 19:40:58 ius which i resolved by adding an explicit library path for expat (in similar fashion as is done for cross gdb)
# 19:41:19 ius but then i run into: mi-cmd-break.c:(.text+0x11d8): undefined reference to `_obstack_free'
# 19:42:19 ius relevant part of build.log: https://p.6core.net/p/n28WD2inT1buV71fjpamXUux
# 19:42:35 ius obstack.o is part of libiberty.a, which is being linked
# 19:43:49 ius obstack.o looks shifty to me though: https://p.6core.net/p/a9vJ9D8DzBXddxHmcrgedz45
# 20:11:02 bhundven ius: I would assume all sorts of issues with uClibc-0.9.xx, it hasn't been maintained for a while.
# 20:18:16 ius hmm, i wouldn't be building such an old uclibc if it wasn't for trying to match a target device im trying to debug
# 20:19:01 bhundven maybe try an older gdb?
# 20:21:06 ius fair enough
# 20:22:06 bhundven if an older gdb works, and you had a lot of time to figure it out, you could bisect gdb to figure out what changed in gdb, and possibly come up with a patch for gdb 7.11
# 20:22:19 bhundven oops
# 20:22:25 bhundven patch for uClibc-0.9
# 20:22:57 bhundven but personally, I don't see uClibc-0.9 lasting much longer in ct-ng
# 20:23:12 wbx newer gdb/binutils introduced _obstack_free, disable OBSTACK in uClibc, so internal obstack implementation is used.
# 20:23:13 bhundven well, in the master branch
# 20:25:28 wbx ius: check your uclibc config and disable obstack
# 20:25:46 ius thanks
# 20:26:00 bhundven thanks, wbx!
# 20:26:57 wbx there was a discussion about it recently on the uClibc-ng mailinglist
# 20:29:12 bhundven wbx: in the uClibc.sh, should I check for newer gdb/binutils and disable obstack?
# 20:30:16 wbx i think that is the best option. need to check if I add the missing symbol so that both configurations will work
# 20:32:11 bhundven wbx: is this newer then 2.26?
# 20:33:09 ius heh, the option doesn't exist yet in 0.9.32
# 20:38:13 bhundven guessing this is in 2.26, as I see the changes from november 2015 in the binutils-gdb tree
# 20:39:30 bhundven so I'll say binutils >= 2.26 and gdb >= 7.11 (as 7.10.1 was from the 7.10 branch)
# 20:42:20 bhundven makes me wonder if someone builds a toolchain with 2.25 binutils and gdb 7.11?
# 20:42:34 bhundven or 2.26 and 7.10.1
# 21:01:24 wbx it is only if you build gdb or binutils for native usage.
# 21:01:38 wbx if you create a cross-compiler it is no issue.
# 21:02:07 wbx it happens when you use your cross-compiler to build gdb or nm for your target.
# 21:02:46 wbx ius: and is there any obstack code ?
# 21:03:42 ius it succesfully built with gdb 7.10.1
# 21:03:51 ius (without touching uclibc)
# 21:04:51 wbx ius: still the question remains, are there any obstack functions unconditionally build into your uClibc?
# 21:05:19 ius let me see
# 21:08:38 ius yes, it was included in 0.9.xx
# 21:08:49 ius File: ./mipsel-unknown-linux-uclibc/sysroot/usr/lib/libc.a(obstack.os)
# 21:16:52 aquarat_ quits : Ping timeout: 244 seconds
# 21:19:06 aquarat joins #crosstool-ng
# 21:23:09 ius uclibc is still incompatible with that gdb ver, fwiw (https://sourceware.org/bugzilla/show_bug.cgi?id=14523)
