You can pass -fPIE to gcc by using the -optc-fPIE flag.
Thanks Ian
Thanks Ian. There's much I don't fully understand about ghc, but I read somewhere that the -optc-* options would only be applied when building via intermediate C files, which isn't happening in the compilation process specified above. Is this incorrect, or have I misunderstood something? In any event, adding -optc-fPIE doesn't remove the error message. That error message is kicked up by uclibc, on account of the hello-cross binary having a TEXTREL section, which I understand it shouldn't have if we're generating PIE or PIC code. The instruction to "use the GCC option -fPIE" is just uclibc's suggestion as to how to avoid this. I also tried adding -fPIE or -fPIC to the "C compiler flags" section in inplace/lib/settings, but this didn't resolve the issue. I also tried using "BuildFlavour = unreg" in mk/build.mk, but this didn't resolve the issue. What I thought to try next is to add llvm/clang to my cross-compiler toolchain, and try building with the -fllvm flag in SRC_HC_OPTS. Other suggestions will be much welcomed.
