| Summary | 0006078: config fails due to -Werror=unused-but-set-parameter while looking for pthreads | ||||
| Description | tl;dr; My problem goes away if I patch in a more recent version of m4/ax_pthread.m4: https://github.com/autoconf-archive/autoconf-archive/blob/9e917efe603b0d756f258cad6eb2056559284ed0/m4/ax_pthread.m4 Can that be done at head? ----- One of the config steps runs a test compile/link that fails with the following error: conftest.c: In function 'routine': conftest.c:36:51: error: parameter 'a' set but not used [-Werror=unused-but-set-parameter] static void routine(void *a) { a = 0; } This in turn make configure assert that pthreads is not available and halt the build. | ||||
| Steps To Reproduce | I encountered this while trying to get a build working for an existing bazel project and I'm still trying to sort out exactly what it's doing different. I *suspect* it's caused by passing -Werror=all or something like that, but I've not been able to sort out exactly what it's doing. However I suspect it would reproduce like this: # BUILD.microhttpd load("@rules_foreign_cc//tools/build_defs:configure.bzl", "configure_make") configure_make( name = "microhttpd", lib_source = "libmicrohttpd-0.9.69", make_commands = ["make"], visibility = ["//visibility:public"], ) # WORKSPACE load("@bazel_tools//tools/build_defs/repo:git.bzl", "git_repository") load("@bazel_tools//tools/build_defs/repo:http.bzl", "http_archive") http_archive( name = "org_gnu_microhttpd", urls = ["https://ftp.gnu.org/gnu/libmicrohttpd/libmicrohttpd-0.9.69.tar.gz"], sha256 = "fb9b6b148b787493e637d3083588711e65cbcb726fa02cee2cd543c5de27e37e", build_file = "@//:BUILD.microhttpd", ) git_repository( name = "rules_foreign_cc", path = "/home/bcs/Documents/rules_foreign_cc", remote = "git://github.com/bazelbuild/rules_foreign_cc.git", commit = "ed3db61a55c13da311d875460938c42ee8bbc2a5", ) load("@rules_foreign_cc//:workspace_definitions.bzl", "rules_foreign_cc_dependencies") rules_foreign_cc_dependencies([]) # CMD bazel build @org_gnu_microhttpd//:microhttpd | ||||
