>From 5c1f6fe53db3f3916776b9e06909e8fc598e7a53 Mon Sep 17 00:00:00 2001 From: Diego Nicola Barbato Date: Tue, 9 Nov 2021 18:24:57 +0100 Subject: [PATCH] gnu: webkitgtk: Really disable SSE2 on i686-linux. This is a followup to d82fd7c2dd542693988f61fb15c020e3209ac7ec. * gnu/packages/patches/webkitgtk-dont-detect-sse2.patch: New file. * gnu/local.mk (dist_patch_DATA): Add it. * gnu/packages/webkit.scm (webkitgtk)[source]: Use it. [arguments]: Remove 'disable-sse2' phase. When building on i686-linux, insert 'setenv' forms in the 'prepare-build-environment' phase that set both 'CFLAGS' and 'CXXFLAGS' to '-march=i686'. --- gnu/local.mk | 1 + .../patches/webkitgtk-dont-detect-sse2.patch | 28 +++++++++++++++++++ gnu/packages/webkit.scm | 17 +++++------ 3 files changed, 36 insertions(+), 10 deletions(-) create mode 100644 gnu/packages/patches/webkitgtk-dont-detect-sse2.patch diff --git a/gnu/local.mk b/gnu/local.mk index 208875754b..438b661442 100644 --- a/gnu/local.mk +++ b/gnu/local.mk @@ -1899,6 +1899,7 @@ dist_patch_DATA = \ %D%/packages/patches/vtk-fix-freetypetools-build-failure.patch \ %D%/packages/patches/vtk-8-fix-freetypetools-build-failure.patch \ %D%/packages/patches/warsow-qfusion-fix-bool-return-type.patch \ + %D%/packages/patches/webkitgtk-dont-detect-sse2.patch \ %D%/packages/patches/webkitgtk-share-store.patch \ %D%/packages/patches/webkitgtk-bind-all-fonts.patch \ %D%/packages/patches/websocketpp-fix-for-cmake-3.15.patch \ diff --git a/gnu/packages/patches/webkitgtk-dont-detect-sse2.patch b/gnu/packages/patches/webkitgtk-dont-detect-sse2.patch new file mode 100644 index 0000000000..6be2775480 --- /dev/null +++ b/gnu/packages/patches/webkitgtk-dont-detect-sse2.patch @@ -0,0 +1,28 @@ +Copied from Debian: + +https://sources.debian.org/data/main/w/webkit2gtk/2.34.1-1/debian/patches/dont-detect-sse2.patch + +From: Alberto Garcia +Subject: Don't check for SSE2 support on i386 +Bug-Debian: https://bugs.debian.org/930935 +Forwarded: no +Index: webkitgtk/Source/cmake/WebKitCompilerFlags.cmake +=================================================================== +--- webkitgtk.orig/Source/cmake/WebKitCompilerFlags.cmake ++++ webkitgtk/Source/cmake/WebKitCompilerFlags.cmake +@@ -148,15 +148,6 @@ if (COMPILER_IS_GCC_OR_CLANG) + if (CMAKE_CXX_COMPILER_ID MATCHES "GNU") + WEBKIT_PREPEND_GLOBAL_COMPILER_FLAGS(-Wno-expansion-to-defined) + endif () +- +- # Force SSE2 fp on x86 builds. +- if (WTF_CPU_X86 AND NOT CMAKE_CROSSCOMPILING) +- WEBKIT_PREPEND_GLOBAL_COMPILER_FLAGS(-msse2 -mfpmath=sse) +- include(DetectSSE2) +- if (NOT SSE2_SUPPORT_FOUND) +- message(FATAL_ERROR "SSE2 support is required to compile WebKit") +- endif () +- endif () + endif () + + if (COMPILER_IS_GCC_OR_CLANG AND NOT MSVC) diff --git a/gnu/packages/webkit.scm b/gnu/packages/webkit.scm index 688e745d95..88a59d7acd 100644 --- a/gnu/packages/webkit.scm +++ b/gnu/packages/webkit.scm @@ -236,7 +236,8 @@ (define-public webkitgtk (sha256 (base32 "1vix0w24m7mq82rzxrk8xvcrkli44gimzs282xs29q2xf0b16g24")) - (patches (search-patches "webkitgtk-share-store.patch" + (patches (search-patches "webkitgtk-dont-detect-sse2.patch" + "webkitgtk-share-store.patch" "webkitgtk-bind-all-fonts.patch")))) (build-system cmake-build-system) (outputs '("out" "doc")) @@ -295,23 +296,19 @@ (define-public webkitgtk (("libWPEBackend-fdo-([\\.0-9]+)\\.so" all version) (string-append wpebackend-fdo "/lib/" all))) #t))) - ,@(if (string-prefix?
