Going with a comment in AddSwift.cmake, I switched the include fag to the library output directory to "-resource-dir”, but then SwiftShims wouldn’t build. So I changed the flag back to a standard include and make it *also* specify “-resource-dir” on cross-compile (so the cross command has both -I and -resource-dir). Now the native host builds, but the cross-compiled stdlib won’t because of the same SwiftShims issue.</div><div class=""><br class=""></div><div class="">So I need to look at how the compiler uses -resource-dir what’s going on with SwiftShims.</div></div><br class=""><blockquote type="cite" class=""><div dir="ltr" class=""><div class=""><div class="gmail_quote"><div style="word-wrap:break-word" class=""><div class=""><div class="">My changes are here: <a href="https://github.com/karwa/swift" target="_blank" class="">https://github.com/karwa/swift</a></div></div><div class=""><br class=""></div><div class="">Then I’m building with:</div><div class=""><br class=""></div><div class=""><div class="">../swift/utils/build-script -d \</div><div class=""><span style="white-space:pre-wrap" class=""> </span>--install-prefix="/usr" \</div><div class=""><span style="white-space:pre-wrap" class=""> </span>--install-symroot="${cc_files}/out/symroot" \</div><div class=""><span style="white-space:pre-wrap" class=""> </span>-- \</div><div class=""><span style="white-space:pre-wrap" class=""> </span>--cross-compile-tools-deployment-targets=linux-armv7 \</div><div class=""><span style="white-space:pre-wrap" class=""> </span>--cross-compile-sysroot="${sysroot}" \</div><div class=""><span style="white-space:pre-wrap" class=""> </span>--cross-compile-toolchain-bin="${toolchain}"</div><div class=""><span style="white-space:pre-wrap" class=""> </span>--stdlib-deployment-targets="macosx-x86_64;linux-armv7=linux-armv7”</div></div></div></div></div></div></blockquote><br class=""></div></div><div>Explanation on the flags, process:</div><div><br class=""></div><div>${cc_files} = the place where I stick the cross-compile resources.
