[Linux] crash with --cpu-mode=1

Hello guys,

without that command --cpu-mode=1 pokemon white edition works fine, but still slow.

If I start Desmume with --cpu-mode=1 the game runs faster. But when I start a Pokemon fight, Desmume always close automatically.

Any ideas how i can use JIT (--cpu-mode=1) without that force close?

Thank you for your help.

Re: [Linux] crash with --cpu-mode=1

I fixed that error, i don't know specifically what was the solution but i tell you what I've done:

I use MINT, that based on Ubuntu. First I installed the new desmume version with ./configure, make and make install. But these steps are not recommended for Ubuntu.

I installed the package "checkinstall", so you dont use "make install" no more, but "checkinstall" now as the last step.

In this topic they discussed this error as well, and an idea was to add "#define NDEBUG" to  arm_jit.h, so I did that.

http://forums.desmume.org/viewtopic.php?id=9681

I runned ./configure again and I saw that some packages were not installed, so I installed them:

libsoundtouch-dev

libzzip-0-13

libzzip-dev

liblua5.1-0-dev

libagg-dev

libosmesa6-dev was missing as well, but after I installed that i got errors after the "make" command.

With this changes I recompiled desmume 0.9.9 again and I was able to fight against other trainers without a crash. So maybe these tips are usefull for someone of you.

Re: [Linux] crash with --cpu-mode=1

Just so you know, using "#define NDEBUG" only masks the error; the actual error will still occur internally. This could cause errors to snowball and ultimately result in undefined behavior. In other words, if there are bugs, "#define NDEBUG" won't magically fix the bugs, but it will stop DeSmuME from immediately crashing out when it sees them.
