Bug #77011 [NEW]: configure cannot detect iconv library on Mojave (macOS 10.14)

From: axnnoindexr11 at gmail dot com Operating system: macOS 10.14 PHP version: 7.3.0RC3 Package: Compile Failure Bug Type: Bug Bug description:configure cannot detect iconv library on Mojave (macOS 10.14) Description: ------------ In Mojave, remove /usr/include and put system headers on only /Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk/usr/include: https://developer.apple.com/documentation/xcode_release_notes/xcode_10_release_notes#3035624 Yesterday, I tried to compile PHP with iconv bundled Mojave, but ./configure reports an error: Please reinstall the iconv library. I researched the reason and I found that shared libraries bundled Mojave have strange extensions, .tbd. ``` $ xcrun --show-sdk-path /Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk $ ls $(xcrun --show-sdk-path)/usr/include/iconv.h /Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk/usr/include/iconv.h $ ls $(xcrun --show-sdk-path)/usr/lib/libiconv.* /Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk/usr/lib/libiconv.2.4.0.tbd /Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk/usr/lib/libiconv.2.tbd /Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk/usr/lib/libiconv.tbd $ ls /usr/include ls: cannot access '/usr/include': No such file or directory $ ls /usr/lib/libiconv.* /usr/lib/libiconv.2.4.0.dylib /usr/lib/libiconv.2.dylib /usr/lib/libiconv.dylib ``` configure of PHP check only .dylib for macOS libraries. Actually, .tbd is also a shared library extension for macOS and make works well after I applied simple patch that also checks .tbd. I want to add .tbd extension support for configure.
