Buildroot for AT91SAM9261_EK (II)

The first try fails. Too bad!
Building was blocked by some funny miniperl issues. It looks not so simple.

ext/util/make_ext: line 122: ../../miniperl: No such file or directory Warning: No Makefile!

Reverse gcc compile:

• gcc 4.3 => gcc 4.1
• g++ 4.3 => g++ 4.1

Max tried to change the configuration in following way. Maybe it works.

Target Architecture (arm)
Target Architecture Variant (arm926t)
Target ABI (OABI)
The rest settings use default ones.

After about 30 minutes, it seems that building success. At least no error message come out. See the root.

Strange!

After some tries, Max located the problem. Building fails due to "EABI", a feature of targeting toolchain to optimize the floating point computation. See the following test.

• gcc 4.3.1 + EBAI => Fail
• gcc 4.1.1 + EBAI => Fail
• gcc 4.3.1 + OBAI => Success
• gcc 4.1.1 + OBAI => Success
