Plugin for pre-built cross-compiler

[Pedro Lopes]

Hello,

I have the option of using the built gcc from Linaro to my target platform.
I want to use this because it is proven to be working and the
configuration is already performed with plugin support (Link to the
binaries: https://releases.linaro.org/components/toolchain/binaries/latest/arm-eabi/
)

The problem I get is when I try to add my plugin using the -fplugin option.
Using gcc 6.3.0, compiled from source to compile my plugin, I get the
following undefined symbols when trying to load my plugin .so into the
gcc 6.3.1 binary:

[plopes@lopes bin]$./arm-eabi-gcc -v
...
GNU C++14 (Linaro GCC 6.3-2017.02) version 6.3.1 20170109 (arm-eabi)
    compiled by GNU C version 4.8.4, GMP version 6.1.0, MPFR version
3.1.4, MPC version 1.0.3, isl version none
GGC heuristics: --param ggc-min-expand=100 --param ggc-min-heapsize=131072
[plopes@lopes bin]$ ./arm-eabi-gcc -S -fplugin=./structsizes.so
-fplugin-arg-structsizes-log=./log.txt test.cxx
cc1plus: error: cannot load plugin ./structsizes.so
   ./structsizes.so: undefined symbol: _ZdlPvm
[plopes@lopes bin]$ c++filt _ZdlPvm
operator delete(void*, unsigned long)

Do I need to use the same compiler version as the one used to compile
the cross-compiler (gcc-4.8.4) to compile my plugin? Does anyone have
any idea how I can solve this?

Kind regards,
Pedro
