According to [this post](https://discourse.itk.org/t/itk-5-1-1-has-been-released/3422), building itk 5.1.1 with gcc 10 is supported now. However, I failed to build it on ArchLinux, gcc 10.2.0. My cmake configuration:

```auto
 cmake -B build -S "ITK-5.1.1" \
  -DBUILD_TESTING=OFF \
  -DBUILD_SHARED_LIBS=ON \
  -DCMAKE_BUILD_TYPE=Release \
  -DCMAKE_INSTALL_PREFIX=/usr \
  -DCMAKE_SKIP_INSTALL_RPATH=ON \
  -DITK_BUILD_DEFAULT_MODULES=ON \
  -DITK_USE_SYSTEM_DOUBLECONVERSION=ON \
  -DITK_USE_SYSTEM_EIGEN=ON \
  -DITK_USE_SYSTEM_EXPAT=ON \
  -DITK_USE_SYSTEM_FFTW=ON \
  -DITK_USE_SYSTEM_GDCM=ON \
  -DITK_USE_SYSTEM_GOOGLETEST=ON \
  -DITK_USE_SYSTEM_HDF5=ON \
  -DITK_USE_SYSTEM_JPEG=ON \
  -DITK_USE_SYSTEM_PNG=ON \
  -DITK_USE_SYSTEM_TIFF=ON \
  -DITK_USE_SYSTEM_ZLIB=ON \
  -DITK_WRAP_PYTHON=ON

```

and here is the complete build log: [itk-5.1.1-buildlog.txt](https://discourse.itk.org/uploads/short-url/7XiQdHvhqPtMK7kijC3vMnnLh9g.txt) (627.4 KB)

I could build it 5.1.1 with gcc8, gcc9 or clang. However, gcc8 and gcc9 will be removed once there is no package in the ArchLinux official repo depends on them.

Does `master` compiles on your system? Does it compile without wrapping (`-DITK_WRAP_PYTHON=OFF`)?

@phcerdan might have some suggestions. The first error message is:

I have been compiling master with gcc10 with no problems. I haven’t tested 5.1.1.

@phcerdan @dzenanz Yeah, I could build itk master branch with gcc 10, with `ITK_WRAP_PYTHON=ON`. Any plan to release 5.1.2?

Following up, `v5.1.2` and `v5.2rc01` are available with GCC 10 support.
