Issue
I want to use OpenEXR in a Bazel project.
My WORKSPACE.bazel look like this:
# OpenEXR
http_archive(
name = "openexr",
build_file = "//third_party:openexr.BUILD",
sha256 = "53126a6a0d29f37336382f4d41afa8cc78b1958628e5e586469503c41af73f1d",
strip_prefix = "openexr-2.2.0",
urls = ["https://github.com/openexr/openexr/archive/v2.2.0.zip"],
)
I am using the openexr.BUILD file provided by seurat
In my BUILD.bazel file I create a test target:
cc_test(
name = "TestOpenEXR",
timeout = "short",
srcs = [
"test_openexr.cpp",
],
deps = [
"@googletest//:gtest_main",
"@openexr//:half",
"@openexr//:iex",
"@openexr//:ilm_imf",
"@openexr//:imath",
],
)
When I try to build this target using Bazel (3.5.0) (bazel build) with Ubuntu 18.04 and gcc 7.5.0 I get the following error:
BUILD.bazel:241:11: C++ compilation of rule '@openexr//:imath' failed (Exit 1) gcc failed: error executing command /usr/bin/gcc -U_FORTIFY_SOURCE -fstack-protector -Wall -Wunused-but-set-parameter -Wno-free-nonheap-object -fno-omit-frame-pointer '-std=c++0x' -MD -MF ... (remaining 49 argument(s) skipped)

I am using a .bazelrc file that should force GCC to use C++17 (as good as it can ;)):
build:gcc --cxxopt=-std=c++17
Any ideas how I can get around the ISO C++1z error?
Solution
In the meantime, I was able to solve the problem. Base on the BUILD file file from seurat I took an up to date master version von OpenEXR and started to fix all issues. The final BUILD.bazel was tested successfully with Ubuntu 16.08 GCC, LLVM and Windows 10 VS2019.
I created my own bazel branch for the OpenEXR: https://github.com/Vertexwahn/openexr/tree/bazel
Update OpenEXR has now official Bazel support.
