From mboxrd@z Thu Jan 1 00:00:00 1970 From: Giulio Benetti Date: Mon, 8 Apr 2019 17:43:11 +0200 Subject: [Buildroot] [PATCH] package/android-tools: fix static linking failure due to lack of deps In-Reply-To: <20190408110431.734b346b@windsurf> References: <20190408110431.734b346b@windsurf> Message-ID: <20190408154311.127351-1-giulio.benetti@micronovasrl.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: buildroot@busybox.net When static linking some dependency library can be missing(i.e. -latomic for -lcrypto) on linking libraries list. This is because when static linking libraries dependencies are not transparently linked into binary. To avoid moving libraries before/after one another or add new ones that are not needed at all in some linking case use `pkg-config --libs LIBRARY` where LIBRARY is the library we "probe" for its existence and dependency. So: - Remove 0005-fix-static-link-zlib.patch where -lcrypto and -lz were swapped - Replace it with 0005-Use-pkgconf-to-get-libs-deps.patch where -lcrypto has been substituted with `pkg-config --libs libcrypto` - Add host-pkgconf to ANDROID_TOOLS_DEPENDENCIES Fixes: http://autobuild.buildroot.net/results/d3d/d3d6679cfc8afe4467368bd3d31483172c1032de/ Signed-off-by: Giulio Benetti --- .../0005-Use-pkgconf-to-get-libs-deps.patch | 35 ++++++++++++++++++ .../0005-fix-static-link-zlib.patch | 36 ------------------- package/android-tools/android-tools.mk | 1 + 3 files changed, 36 insertions(+), 36 deletions(-) create mode 100644 package/android-tools/0005-Use-pkgconf-to-get-libs-deps.patch delete mode 100644 package/android-tools/0005-fix-static-link-zlib.patch diff --git a/package/android-tools/0005-Use-pkgconf-to-get-libs-deps.patch b/package/android-tools/0005-Use-pkgconf-to-get-libs-deps.patch new file mode 100644 index 0000000000..63ea1fb6a4 --- /dev/null +++ b/package/android-tools/0005-Use-pkgconf-to-get-libs-deps.patch @@ -0,0 +1,35 @@ +makefiles: use pkgconf to get libs deps + +LIBS lists library dependencies without taking into account static linking +that need ordered listing and more libraries listed since differently from +shared linking dependency is not transparent(i.e. -lcrypto could need +-latomic etc.). + +Replace -lcrypto with `pkg-config --libs libcrypto` command to be sure all +needed libraries are listed during linking. + +Signed-off-by: Giulio Benetti +--- +diff -urpN android-tools-4.2.2+git20130218.orig/debian/makefiles/adbd.mk android-tools-4.2.2+git20130218/debian/makefiles/adbd.mk +--- android-tools-4.2.2+git20130218.orig/debian/makefiles/adbd.mk 2019-04-08 16:05:02.967710428 +0200 ++++ android-tools-4.2.2+git20130218/debian/makefiles/adbd.mk 2019-04-08 16:30:42.463084426 +0200 +@@ -44,7 +44,7 @@ CPPFLAGS+= -DADBD_NON_ANDROID + CPPFLAGS+= -I$(SRCDIR)/core/adbd + CPPFLAGS+= -I$(SRCDIR)/core/include + +-LIBS+= -lc -lpthread -lz -lcrypto -lcrypt ++LIBS+= -lc -lpthread -lz `pkg-config --libs libcrypto` -lcrypt + + OBJS= $(patsubst %, %.o, $(basename $(SRCS))) + +diff -urpN android-tools-4.2.2+git20130218.orig/debian/makefiles/adb.mk android-tools-4.2.2+git20130218/debian/makefiles/adb.mk +--- android-tools-4.2.2+git20130218.orig/debian/makefiles/adb.mk 2019-04-08 16:05:02.959701400 +0200 ++++ android-tools-4.2.2+git20130218/debian/makefiles/adb.mk 2019-04-08 16:31:06.529426250 +0200 +@@ -41,7 +41,7 @@ CPPFLAGS+= -DHAVE_TERMIO_H + CPPFLAGS+= -I$(SRCDIR)/core/adb + CPPFLAGS+= -I$(SRCDIR)/core/include + +-LIBS+= -lc -lpthread -lz -lcrypto ++LIBS+= -lc -lpthread -lz `pkg-config --libs libcrypto` + + OBJS= $(SRCS:.c=.o) diff --git a/package/android-tools/0005-fix-static-link-zlib.patch b/package/android-tools/0005-fix-static-link-zlib.patch deleted file mode 100644 index dff4df6e79..0000000000 --- a/package/android-tools/0005-fix-static-link-zlib.patch +++ /dev/null @@ -1,36 +0,0 @@ -Fix static linking of adb/adbd - -Both adb and adbd use OpenSSL, which indirectly uses zlib.
