Unsupported jump between ISA modes; consider recompiling with interlinking enabled

[karra]

Hi Folks,

When trying to compile a package I am facing this error .

Background about the question:

1. I am using MIPS architecture
2. I have a live555 package and the main Makefile for this is being generated from cmake of the repository (lets say "repository A") where the live555 is present
3. I have openwrt packages in totally another repository ("repository B"). the Makefile for a particular package calls the cmake file of respository A and compiles the live555 when necessary

Lets say I want to compile package X in the openwrt repository (repository B)

Steps I have followed :

1. When I compile manually, the live555 directory by providing STAGING_DIR, PATH, generating Makefile for target architecture and run make, the libraries will get generated successfully. And even the package X in openwrt (repository B) will get compiled successfully

2. But when I generate the Makefile for live555 using cmake of repository A, the object files for target architecture will get generated but when I try to compile the package X in openwrt (repository B), the compilation fails.

The error I face is

rtcp_from_spec.c:(.text+0x350): Unsupported jump between ISA modes; consider recompiling with interlinking enabled
rtcp_from_spec.c:(.text+0x388): Unsupported jump between ISA modes; consider recompiling with interlinking enabled

When searched about this I found

1. a patch for kernel, but the kernel is already updated - https://lore.kernel.org/patchwork/patch/852646/
2. using the flags -minterlink-mips16 -mno-interlink-mips16

Even after using the flags, I was facing same error.

Any help would be appreciated

Dont know the eaxct reason but the issue got resolved when I removed the optimisation (-O2) flag from live555 config file.

Now the package from openwrt repository is getting successfully compiled.
