Seems a bug. I will confirm it when I got time.

What is the minimum version of GCC and G++ to build it ?
Im thinking is something related to it, i used gcc version 4.9.2 (Debian 4.9.2-10)

I even tried building it natively on an ARM V7 machine (not pi) just using:

./configure --with-http-api --with-stream-caster --with-stat --jobs=8

It builds successfully, but does not run.

I see no errors on output, all libraries are present:

    linux-vdso.so.1 =>  (0x7ebde000)
    /usr/lib/arm-linux-gnueabihf/libcofi_rpi.so (0x76fa9000)
    libdl.so.2 => /lib/arm-linux-gnueabihf/libdl.so.2 (0x76f8f000)
    libstdc++.so.6 => /usr/lib/arm-linux-gnueabihf/libstdc++.so.6 (0x76ebd000)
    libm.so.6 => /lib/arm-linux-gnueabihf/libm.so.6 (0x76e4c000)
    libgcc_s.so.1 => /lib/arm-linux-gnueabihf/libgcc_s.so.1 (0x76e24000)
    libc.so.6 => /lib/arm-linux-gnueabihf/libc.so.6 (0x76cf4000)
    /lib/ld-linux-armhf.so.3 (0x54b46000)

Very strange.

You must specifies the ./configure --arm, for SRS will patch the ST(state-threads) for ARM.
And u can specifies other cross build tools, please read https://github.com/simple-rtmp-server/srs/wiki/v1_EN_SrsLinuxArm#use-other-cross-build-tools

Well today I tried two different ways, I built it using a Debian machine with cross-build-essential and --arm flag, and it compiles fine, but still don't run.

Then I tried with less options, like disable hls, hds and stream-caster but no luck either.
I'm out of ideas what could be.

The raspberrypi is armv7, seems ok to run SRS, but I have not test it.
BTW, is SRS1 ok? Can you try it: http://ossrs.net/srs.release/releases/files/SRS-Ubuntu12-armv7cpu-1.0.30.zip
I will build and run in respberry-py later.

I find a bug for cross build, introduced by SRS2 configure script refined.
Please update code, then build SRS:

./configure --arm && make

Then copy the objs/srs to your armv7 os.

Then I got another segment fault:

I finger it out, the ubuntu14 gcc/g++ version too high, which changed the longjmp context buffer layout, then cause srs/st to crash.

The version of ubuntu14 gcc/g++ to cross build srs: 4.7.3
The version which srs is ok to run on armv7, debian: 4.6.4

For gcc 4.7.3, gdb the research/arm/jmp_sp.cpp:

(gdb) p $sp
$1 = (void *) 0xbefff668

Nothing match the sp.

For gcc 4.6.3, gdb the file:

I will try to fix the high version of gcc for arm, maybe we can use the x86-64 st setjmp and longjmp.

@winlinvip
Copy link
Member

It's very hard to implments the setjmp and longjmp for arm for me.
I just error when glibc > 2.15.
That is, for this bug, you can build srs direclty on your armv7, not use the cross build which gcc tools glibc >2.15.
Or, for SRS:

  1. all i386/x86_64/amd64 are ok.
  2. arm only support glibc < 2.15.

I have tried your armv7 debian server, glibc is ok, srs is built to /root/srs/trunk/objs/srs

@winlinvip
Copy link
Member

I have confirmed:

  1. SRS3 introduced some bug
  2. Ubuntu cross build tool upgraded to 4.7.3, which changed the setjmp and longjmp of glibc 2.15+, this make st(state-threads) corrupt.

For 1, I have fixed it, please use 2.0.192.
For 2, it's impossible to fix it, there is a workaround, you can build srs by gcc 4.6.3 or directly build on your armv7 server(which gcc is 4.6.3).

What happended when all gcc upgrade to 4.7? SRS cannot run on ARM, maybe SRS will migrate to GO, haha.

Directly build on your server:

U can use the following url to visit your arm server:
