Hi Again,
The idea that comes to my mind is the following: would it be possible to
cross-compile the openjfx on the 64 bit Linux using 64 bit tools, but
targeted at 32 bit Linux? What would have to be changed in build
environment to accomplish that? I imagine the environment would have to
have access to headers and development libraries of the 32 bit Linux
system - that's no problem - I would just mount the root of a 32 bit
Ubuntu to some directory, but then I would have to force all tools to
use that path instead of the running system one. And the gcc would have
to be given some cross-compiling options too, I guess...

Hi,
I'm new to this list and I have searched the archives, but haven't

I'm trying to debug a crash in a native part of WebKit-JavaFX bindings
(https://javafx-jira.kenai.com/browse/RT-33599). I have only been able
to reproduce it on 32 bit platforms (Windows and Linux so far). I'm
trying to build the WebKit natives with debugging symbols, so that I
can pin-point the location of the crash in code using gdb. I have
managed to do this successfully on 64 bit Linux, producing 1.7 GB
large libjfxwebkit.so. But on 32 bit Linux, where only I can reproduce
the crash, the build fails with linker error: "memory exhausted" when
trying to assemble the libjfxwebkit.so from object files. So far I
have not been successful in my attempts to circumvent this build
error. I fave tried the following:
- added '--no-keep-memory' to linker options. The man page says about it:
ld normally optimizes for speed over memory usage by
caching the symbol tables of input files in memory. This option tells
ld to instead optimize for memory usage, by
rereading the symbol tables as necessary. This may be
required if ld runs out of memory space while linking a large executable.
- booted the 64bit Ubuntu system and chrooted into a 32 bit
environment. Some say that with 64 bit kernel, each 32 bit user-space
process has more address space than with 32 bit kernel.
- both of the above
My question to the list is: How do you guys produce 32 bit
libjfxwebkit.so with debugging symbols? Have you been able to? Do you
have any special tricks in your sleeves?
Regards,
Peter
