From eb3aac20c879b9532cd3b678efb2126adcd07af7 Mon Sep 17 00:00:00 2001 From: est31 Date: Wed, 29 Jul 2015 11:54:27 +0200 Subject: Android: fix horrible libiconv build Before, our libiconv build was a joke. We first called configure for our own build host system, then called make, before we executed a Android.mk script we provided as patch. The first "native make" always failed, and the LIBICONV_LIB file setting in our Makefile didn't match the built one, resulting in an always-rebuild of iconv. This commit cleans up this total mess, removes the double-build, and the Android.mk, and properly calls ./configure with the according target platform, and uses a built toolchain. As we have to deal with the android bug "NDK: Support for prebuild libs with full sonames" https://code.google.com/p/android/issues/detail?id=55868 as the 2013 patch https://lists.gnu.org/archive/html/libtool-patches/2013-06/msg00002.html by Google's David Turner wasn't inside the 2011 libtool, we pass -avoid-version to libtool. Thanks to the proper build, wide_to_utf8 works for android now, removing us of the need to disable it. --- build/android/Makefile | 73 +++++++++++++++++---------------- build/android/jni/Android.mk | 8 ++-- build/android/libiconv_android_mk.patch | 51 ----------------------- build/android/libiconv_stdio.patch | 7 +++- src/util/string.cpp | 12 ------ 5 files changed, 47 insertions(+), 104 deletions(-) delete mode 100644 build/android/libiconv_android_mk.patch diff --git a/build/android/Makefile b/build/android/Makefile index b87199541..295ddf620 100644 --- a/build/android/Makefile +++ b/build/android/Makefile @@ -133,7 +133,7 @@ FREETYPE_URL_GIT = https://github.com/cdave1/freetype2-android ICONV_VERSION = 1.14 ICONV_DIR = $(ROOT)/deps/libiconv/ -ICONV_LIB = $(ICONV_DIR)/iconv.so +ICONV_LIB = $(ICONV_DIR)/lib/.libs/libiconv.so ICONV_TIMESTAMP = $(ICONV_DIR)timestamp ICONV_TIMESTAMP_INT = $(ROOT)/deps/iconv_timestamp ICONV_URL_HTTP = http://ftp.gnu.org/pub/gnu/libiconv/libiconv-$(ICONV_VERSION).tar.gz @@ -445,52 +445,55 @@ $(ICONV_TIMESTAMP) : iconv_download fi iconv_download : - @if [ !
