Because of some trouble on another project, I wanted to recheck the current nghttp2 build between our mutual dependencies and httpd... and something isn't looking so healthy in the CMake build of the last release. (But I did answer my question, bazel shouldn't be failing to build nghttp2, it is rock hard stable in terms of building rev 1.39.1) CMake is rev 3.9.4 in this example of our build below.
Just as an aside this is all a byproduct of the mak/Makefile.build-win script of https://github.com/appsuite/oss-httpd-build if anyone wants to replicate. Sadly, the gather and preconfig steps still require WSU - some unix on top of Windows for a bash environment. But that build-win nmake logic is what gets us to this... cd httpd-2.4.39 && cmake -G "NMake Makefiles" -D CMAKE_BUILD_TYPE=RelWithDebInfo -D CMAKE_COLOR_MAKEFILE=OFF -D CMAKE_INSTALL_PREFIX=C:\Users\wrowe\dev\oss-httpd-build\dst\httpd-2.4.39-today C:\Users\wrowe\dev\oss-httpd-build\src/httpd-2.4.39 && cd .. -- The C compiler identification is MSVC 19.11.25547.0 -- Check for working C compiler: C:/Program Files (x86)/Microsoft Visual Studio/2017/Enterprise/VC/Tools/MSVC/14.11.25503/bin/Hostx64/x64/cl.exe -- Check for working C compiler: C:/Program Files (x86)/Microsoft Visual Studio/2017/Enterprise/VC/Tools/MSVC/14.11.25503/bin/Hostx64/x64/cl.exe -- works -- Detecting C compiler ABI info -- Detecting C compiler ABI info - done -- Found LibXml2: C:/Users/wrowe/dev/oss-httpd-build/dst/httpd-2.4.39-today/lib/libxml2.lib (found version "2.9.9") -- Found Lua51: C:/Users/wrowe/dev/oss-httpd-build/dst/httpd-2.4.39-today/lib/lua.lib -- Found OpenSSL: C:/Users/wrowe/dev/oss-httpd-build/dst/httpd-2.4.39-today/lib/libcrypto.lib (found version "1.1.1c") -- Found ZLIB: C:/Users/wrowe/dev/oss-httpd-build/dst/httpd-2.4.39-today/lib/zlib.lib (found version "1.2.11") -- Looking for APR_HAS_XLATE -- Looking for APR_HAS_XLATE - found -- Performing Test APR_HAS_XLATE -- Performing Test APR_HAS_XLATE - Failed -- Looking for APU_HAVE_CRYPTO -- Looking for APU_HAVE_CRYPTO - found -- Performing Test APU_HAVE_CRYPTO -- Performing Test APU_HAVE_CRYPTO - Success -- Performing Test APR_HAS_LDAP -- Performing Test APR_HAS_LDAP - Success -- -- Summary of feature detection: -- -- LIBXML2_FOUND ............ : TRUE -- LUA51_FOUND .............. : TRUE -- NGHTTP2_FOUND ............ : TRUE -- OPENSSL_FOUND ............ : TRUE -- ZLIB_FOUND ............... : TRUE -- BROTLI_FOUND ............. : TRUE -- APR_HAS_LDAP ............. : TRUE -- APR_HAS_XLATE ............ : FALSE -- APU_HAVE_CRYPTO .......... : TRUE -- CMake Warning (dev) at CMakeLists.txt:520 (ELSEIF): Policy CMP0054 is not set: Only interpret if() arguments as variables or keywords when unquoted.
