And built successfully when configured like this:
../gdb/configure --target=frv-elf --prefix=/home/joel/test-gdb/install
--enable-sim-hardware --enable-sim --enable-sim-trace
"gdb" as in toplevel from a gdb checkout, I presume.
(If from the gdb subdir I guess you wouldn't get very far.)
Is that why you have to add those options?
I added those options because that is the combination that initially
tripped the failure months ago. Then last week someone spotted
that mingw failed to build. Mike Frysinger and I have been trying to
come up with a configure solution that handles mingw not supporting
dv-sockser.o and some simulators always requiring it.
One major difference is that I use the toplevel configure after
a checkout of *the "sim" CVS module*, so not much of gdb there,
actually just MAINTAINERS and version.in.
I don't think that's really much of an issue. Except to increase my
build time.
I have a fix in my local tree and posted it to the list. Here is my test
plan.
I regenerated all of the sim directories where configure.ac includes
acinclude.m4.
That resulted in the following set of modified files on my working git
branch:
# modified: bfin/configure
# modified: common/acinclude.m4
# modified: cris/configure
# modified: frv/configure
# modified: iq2000/configure
# modified: lm32/configure
# modified: m32r/configure
# modified: m68hc11/configure
# modified: mips/configure
# modified: mn10300/configure
# modified: sh64/configure
Based on that, I put together the following list of targets:
bfin-elf
cris-elf
frv-elf
iq2000-elf
lm32-elf
m32r-elfle
m68hc11-elf
mips-elf
mipstx93-elf
mn10300-elf
sh64-elf
For each of those targets, I will build with no sim-hardware argument,
--enable-sim-hardware, and --disable-sim-hardware. If the configure
and make complete successfully, I will run make check.
Any other suggestions on how to test this?
I can hop on IRC if you give me a channel so we can work through
this quickly. Other forms of chat are OK also. I want to run this down
so a release can happen.
Sometimes I'm at irc.oftc.net#gcc
