From 7d0271b5c30f86e4af175a5ab7df5e593cd85195 Mon Sep 17 00:00:00 2001 From: Russell Yanofsky Date: Tue, 22 Sep 2020 14:31:35 -0400 Subject: [PATCH] depends: Set CMAKE_INSTALL_RPATH for native packages After #19685 started setting LDFLAGS, the INSTALL_RPATH_USE_LINK_PATH cmake option used in the libmultiprocess build no longer works, so it is neccessary to set CMAKE_INSTALL_RPATH as a fallback. It's unclear currently whether the bad interaction between INSTALL_RPATH_USE_LINK_PATH and LDFLAGS is a bug, but the issue is reported: https://github.com/bitcoin/bitcoin/issues/19981#issuecomment-696680877 https://discourse.cmake.org/t/install-rpath-use-link-path-not-working-when-cmake-exe-linker-flags-ldflags-is-set/1892 Commands useful for building / testing this change make -C depends MULTIPROCESS=1 print-libmultiprocess_cmake make -C depends MULTIPROCESS=1 print-native_libmultiprocess_cmake make -C depends MULTIPROCESS=1 HOST=x86_64-apple-darwin16 print-libmultiprocess_cmake rm -rvf depends/x86_64-pc-linux-gnu/native depends/work/staging depends/work/build make -C depends MULTIPROCESS=1 V=1 native_libmultiprocess_staged for f in `find -name mpgen`; do echo == $f ==; readelf -d $f | grep -i path; done make -C depends MULTIPROCESS=1 V=1 native_libmultiprocess_built find -name CMakeCache.txt Fixes #19981 --- depends/funcs.mk | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/depends/funcs.mk b/depends/funcs.mk index 58d882eb053..5697bd6f15d 100644 --- a/depends/funcs.mk +++ b/depends/funcs.mk @@ -163,7 +163,9 @@ $(1)_cmake=env CC="$$($(1)_cc)" \ CXXFLAGS="$$($(1)_cppflags) $$($(1)_cxxflags)" \ LDFLAGS="$$($(1)_ldflags)" \ cmake -DCMAKE_INSTALL_PREFIX:PATH="$$($($(1)_type)_prefix)" -ifneq ($($(1)_type),build) +ifeq ($($(1)_type),build) +$(1)_cmake += -DCMAKE_INSTALL_RPATH:PATH="$$($($(1)_type)_prefix)/lib" +else ifneq ($(host),$(build)) $(1)_cmake += -DCMAKE_SYSTEM_NAME=$($(host_os)_cmake_system) $(1)_cmake += -DCMAKE_C_COMPILER_TARGET=$(host)
