Compile Apache Traffic Server to AC68u

[tramchamploo]

The latest version of ATS uses C++17, so

 ./configure CXX=arm-uclibc-g++ CC=arm-uclibc-gcc --prefix=/opt --host=arm-linux

doesn't work, using am-toolchain. Then I downloaded official arm toolchain and compile with

./configure CXX="arm-none-eabi-g++  --specs=nosys.specs" CC="arm-none-eabi-gcc  --specs=nosys.specs" --prefix=/opt --host=arm-linux

and no luck. Prompting error: You are trying to build on a 32-bit platform, which is unsupported.
This is weird because I'm doing this on x86_64 platform.
What can I do now? Thanks.

This cross-compiler is still 32-bit format! If you are building in a 64bit environment, some.additional libs for handling 32-bit execs in 64bit environment are needed.

I have all libs mentioned in that link, and the toolchain I use is `gcc-arm-none-eabi-10.3-2021.10-x86_64-linux.tar.bz2 ` which is a cross compiler from X86_64 to ARM32.

Are you sure, that you have chosen the right toolchain? Please choose a toolchain intended to compile firmware for AC68U! Your toolchain uses newlib, AC68U needs a toolchain based on uclibc.

So the question is where can I get that kind of toolchain supporting C++17?

 

[st_ty_]

I have to revise the statement in my first post: Building ATS should work, if c++ cross-compiler of your toolchain supports C++17. (But I don't know neither if it really supports C++17 nor if compiled ATS will run without error afterwards on AC-RT68U.)
Try to include "--enable-32bit-build" to configure. According to content of configure.ac, this could solve your problem.

merlin toolchain has no support for C++17, and I don't know any other way to get a toolchain that works for ac68u

Apache 2 is built over in entware space - unless one has very specific requirements to build against apache2 source, would be easier to get entware up and running and go from there...

 

[tramchamploo]

I have very limited knowledge on Makefile, entware makes me confused. I'm trying to use crosstool-ng to build a custom toolchain that is compatible with ac68u which is very challenging.

Not sure that we can help you then...

Entware - there's a number of walk-thrus on the site here that can help you out.

Going into crosstool and makefiles - sounds like you are ill-prepared to go down that path, so I would recommend doing the entware thing if your heart is tied to getting apache2 running on asuswrt...
