Compilation error in cont.c

[Emanuele Ricci]

Hi,
with ruby 1.9.0-1, I get the following error during the
cross-compilation :

cont.o -c cont.c
cont.c: In function `cont_restore_0':
cont.c:327: error: structure has no member named `machine_stack_src'
make: *** [cont.o] Error 1

This code seems not to be usually compiled.

Thanks,
Emanuele.

Could you try the trunk from the svn repo?

We also need you platform information. 1.9.0-1 was compiled without
any problem on my Linux box.

Thank you very much for answering Matsumoto-sensei,

I just tried to cross compile ruby 1.9 trunk getting the same error:

arm-linux-gcc -mbig-endian -I. -I.ext/include/arm-linux -I./include
-I. -DRUBY_EXPORT -D_GNU_SOURCE=1 -o cont.o -c cont.c
cont.c: In function `cont_restore_0':
cont.c:326: error: structure has no member named `machine_stack_size'
make: *** [cont.o] Error 1

I'm cross compiling ruby for an arm processor embedded device on an
ubuntu gutsy gibbon vm using the embedded device compiler tool chain.

So from the configure log:
checking build system type... i686-pc-linux-gnu
checking host system type... arm-unknown-linux-gnu
checking target system type... arm-unknown-linux-gnu
checking for arm-linux-gcc... arm-linux-gcc
checking for arm-linux-gcc... (cached) arm-linux-gcc

I configured it with exactly the same options I used to succesfully
cross compile ruby 1.8.6 p114:
/configure --host=arm-linux CFLAGS=-mbig-endian LDFLAGS=-mbig-endian

Please tell me if any other info could be useful.

Thanks,
Emanuele.

Thank you really very much for patching the trunk, indeed now I'm able
to cross compile succesfully ruby 1.9.

However once I put it on the target and launch it I get the following
error:

ruby1.9: /lib/librt.so.1: no version information available (required by
ruby1.9)
Segmentation fault

Could you give me an hint also about that?

Thank you again,
Emanuele.

That seems to be a linker problem around librt. You have to check
whether librt installed correctly. Or you can remove -lrt from
configure. I have virtually zero knowledge about cross compiling, but
it should be possible.

Hi,
removing -lrt I get the following error:
/libruby-static.a(time.o)(.text+0x198): In function `time_init':
: undefined reference to `clock_gettime'
collect2: ld returned 1 exit status
make[1]: *** [ruby] Error 1
make[1]: Leaving directory `/home/del/Desktop/rubytrunk/ruby'
make: *** [all] Error 2

The "no version information available" kind of error seems to be the
result of a library mismatch between the build and target systems
(http://answers.google.com/answers/threadview?id=786136).

I'll tell you as soon as I get it to work.

By "removing -lrt", I also meant removing HAVE_CLOCK_GETTIME from
<config.h>.

Hi,
I should have read time.c. Indeed removing HAVE_CLOCK_GETTIME I'm able
to get to the end of the compilation process.
I still get the "Segmentation error" trying the resulting ruby on the
target, doe.
I guess I must recompile the glibc libraries to match those of the
building system...

I hope you can solve the version inconsistency.

Me too, trying to cross-compile the glibc libraries right now.

Thank you again,
Emanuele.
