MPC5748G position independent code

Hi,

I am trying to compile the hello sample project for MPC5748G with -fPIC flag in the compiler.

I am getting compiler error that refer to missing assembly commands:

Hello,

unfortunately, there is a compiler bug in S32 Design Studio version 1.1 which does not allow to use -fPIC switch. But do not worry, this bug is fixed in S32 Design Studio v1.2 which will be released at the end of May.

I am sorry for any inconvenience.

Regards,

Martin

Hi Martin,

Is there a way to compile it without S32? is it a bug in the IDE or the compiler itself?

Does other compilers support it such as Diab compiler for example?

Hello,

I am not compiler expert and I do not know all dependencies, but it seems it is compiler bug not IDE bug. But it is fixed in next release.

I do not know Diab compiler but I assume that it supports this feature.

Regards,

Martin
