ARM toolchains with NPTL for Asuswrt/Merlin

[Vexira]

Has anyone tested an 88u with such changes or the 382 beta?

Yes, I had to update an environment variable RTVER in this file, ~/asuswrt-merlin/release/src-rt/platform.mak. And the Beceem_BCMS250_arm with prebuilt librt.so had to be updated too.

Unfortunately, your build of the toolchain, I had issues with some custom programs. Transmission-daemon wouldn't start up and nothing in the syslog about it. And Cryptsetup got a segfault when I tried mounting an encrypted disk.

RTVER reminds a thing and I fired up my dusty VM. Here is what I have to make use of the new uClibc/pthread lib for RT-AC56U.

Before make

sed -i '19s/0.9.32.1/0.9.33.2/' ../src-rt/platform.mak
sed -i '8s/0.9.32.1/0.9.33.2/' router/Beceem_BCMS250_arm/Makefile

After make

# fix dangling 0.9.32.1 libs
#rm -f router/arm-uclibc/target/lib/librt-0.9.32.1.so
#rm -f router/arm-uclibc/target/lib/librt.so
rm -f router/arm-uclibc/target/lib/libgcc_s.so.1

cp ~/hndtools/hndtools-arm-linux-2.6.36-uclibc-4.5.3/arm-brcm-linux-uclibcgnueabi/sysroot/lib/libgcc_s.so.1 router/arm-uclibc/target/lib

cp ~/hndtools/hndtools-arm-linux-2.6.36-uclibc-4.5.3/arm-brcm-linux-uclibcgnueabi/sysroot/lib/librt.so.0 router/arm-uclibc/target/lib

Then make gen image again. Can't recall why I had later commented out librt*

The newer uClibc and pthread library benefit user space programs. The firmware (as of RT-AC56U) has little multithreaded applications. The uClibc and native pthread combination has some performance edge over Entware-ng's equivalent but Entware-ng is more convenient to work with.

When using your toolchain, today I confirmed that running Transmission results in only one process. This is good. And with Asuswrt-Merlin toolchain (Linux threads), there is five processes.
