LinuxにObjective-C 2.0環境作成

前回の方法だとプロパティとか高速列挙とかのObjective-C 2.0の機能を利用できないはず。

で、それらを利用したい場合の環境構築。

条件としては
・最新のGNUstepをインストールする。
・ソースのコンパイルにはgccではなくclangを使う（GNUstepのコンパイル自体はgccでOK）。

OSはFedora 13を使った。理由はclangをyumでインストールできて簡単だから。

まずclang（とllvm）をインストール
↓
# yum install clang clang-devel llvm

次に最新のGNUstepを入手
↓
# cd /usr/local/src
# svn co svn://svn.gna.org/svn/gnustep/trunk gnustep

で、make、base、gui、backの順にビルド＆インストールしていく。基本的な手順は前回と同じ。

【gnustep-makeのインストール】

# cd /usr/include
# ln -s /usr/lib/libffi-3.0.9/include/ffi.h .
# ln -s /usr/lib/libffi-3.0.9/include/ffitarget.h .

# cd /usr/local/src/gnustep/modules/core/make
# ./configure --with-layout=fhs --prefix=/usr
# mkdir -p /root/rpmbuild/{BUILD,BUILDROOT,RPMS,SOURCES,SPECS,SRPMS}　（もしディレクトリがなければ）

前回と同じで、RPM化しないならmake installで良い。checkinstallでRPM化する場合はRPMファイルのファイル名を修正するために以下のような手間をかける。この辺はbase、gui、backでも同様。バージョンはVersionファイルを見れば分かる。

# checkinstall --inspect

The package documentation directory ./doc-pak does not exist.
Should I create a default set of package docs? [y]:

パッケージのドキュメンテーションを準備..OK

GSMDNSNetServices.mはmDNS関連のコードっぽい。とりあえずいらないのでconfigureのオプションを変える。

# ./configure --prefix=/usr --disable-zeroconf
# make
# checkinstall --inspect
# cd /root/rpmbuild/RPMS/i386
# rpm -ivh gnustep-base-1.21.1-1.i386.rpm

【gnustep-guiのインストール】

# cd /usr/local/src/gnustep/modules/core/gui
# yum install libjpeg-devel libtiff-devel libpng-devel
# ./configure --prefix=/usr
# make
# checkinstall --inspect
# cd /root/rpmbuild/RPMS/i386
# rpm -ivh gnustep-gui-0.19.0-1.i386.rpm

【gnustep-backのインストール】

# yum install libX11-devel libXt-devel freetype-devel libart_lgpl-devel libXext-devel
# cd /usr/local/src/gnustep/modules/core/back
# ./configure --prefix=/usr
# make
# checkinstall --inspect
# cd /root/rpmbuild/RPMS/i386
# rpm -ivh gnustep-back-0.19.0-1.i386.rpm

【試しにObjective-Cのソースコンパイルと実行】

ヘッダファイル： Class1.h, Class2.h
ソースファイル： Class1.m, Class2.m

をコンパイルするとすると、前回と違うのはMakefile。こんな感じ
↓
CC        = clang
CFLAGS    = -O2 -fconstant-string-class=NSConstantString
LIBS        = -lgnustep-base -lobjc
OBJS        = Class1.o Class2.o
TARGET    = a.out

$(TARGET): $(OBJS)
            $(CC) -o $@ $(OBJS) $(LIBS)

%.o: %.m
            $(CC) $(CFLAGS) -c $*.m -o $*.o

clean:
            rm -f $(TARGET) $(OBJS)

CentOS 5.4にObjective-C環境作成

インストールするものをRPM化したかったから

# checkinstall --inspect

して

# cd /usr/src/redhat/RPMS/i386
# rpm -ivh ～.rpm

でインストールしてるけど、特に必要ない人はそれぞれ

# make

の後

#make install

で良い。

【libffiのインストール】

http://sourceware.org/libffi/
とかから
libffi-3.0.9.tar.gz
をダウンロード。

# tar zxf libffi-3.0.9.tar.gz
# ./configure --prefix=/usr
# make
# checkinstall --inspect

インストール時に

ファイル /usr/share/info/dir (パッケージ libffi-3.0.9-1.i386 から) は、パッケージ info-4.8-14.el5.i386 からのファイルと競合しています。

とかエラーが出るのでvi編集画面で/usr/share/info/dirの行を削除。

# cd /usr/src/redhat/RPMS/i386
# rpm -ivh libffi-3.0.9-1.i386.rpm

/usr/includeにヘッダファイルがインストールされないから、

# cd /usr/include
# ln -s /usr/lib/libffi-3.0.9/include/ffi.h .
# ln -s /usr/lib/libffi-3.0.9/include/ffitarget.h .

次に
http://www.gnustep.org/
から
gnustep-make-2.2.0.tar.gz
gnustep-base-1.19.3.tar.gz
gnustep-gui-0.16.0.tar.gz
gnustep-back-0.16.0.tar.gz
をダウンロード

【gnustep-makeのインストール】

# tar zxf gnustep-make-2.2.0.tar.gz
# ./configure --with-layout=fhs --prefix=/usr
# checkinstall --inspect
# cd /usr/src/redhat/RPMS/i386
# rpm -ivh gnustep-make-2.2.0-1.i386.rpm
# sh /usr/share/GNUstep/Makefiles/GNUstep.sh
# export GNUSTEP_MAKEFILES=/usr/share/GNUstep/Makefiles

【gnustep-baseのインストール】

# tar zxf gnustep-base-1.19.3.tar.gz
# ./configure --prefix=/usr
# make
# checkinstall --inspect
# cd /usr/src/redhat/RPMS/i386
# rpm -ivh gnustep-base-1.19.3-1.i386.rpm

【gnustep-guiのインストール】

# yum install libjpeg-devel
# yum install libtiff-devel
# yum install libpng-devel
# tar zxf gnustep-gui-0.17.1.tar.gz
# ./configure --prefix=/usr
# make
# checkinstall --inspect
# cd /usr/src/redhat/RPMS/i386
# rpm -ivh gnustep-gui-0.17.1-1.i386.rpm

【gnustep-backのインストール】

# yum install libX11-devel
# yum install libXt-devel
# yum install freetype-devel
# yum install libart_lgpl-devel
# tar zxf gnustep-back-0.17.1.tar.gz
# ./configure --prefix=/usr
# make
# checkinstall --inspect
# cd /usr/src/redhat/RPMS/i386
# rpm -ivh gnustep-back-0.17.1-1.i386.rpm

【試しにObjective-Cのソースコンパイルと実行】

ヘッダファイル： Class1.h, Class2.h
ソースファイル： Class1.m, Class2.m

をコンパイルするとする。

Makefileはこんな感じ↓

CC        = gcc
CFLAGS    = -O2 -fconstant-string-class=NSConstantString
INCLUDES    = Class1.h Class2.h
LIBS        = -lgnustep-base
OBJS        = Class1.o Class2.o
TARGET    = a.out

$(TARGET): $(OBJS)
            $(CC) -o $@ $(OBJS) $(LIBS)

%.o: %.m
            $(CC) $(CFLAGS) -c $*.m -o $*.o

clean:
            rm -f $(TARGET) $(OBJS)

ポイントは、
-fconstant-string-class=NSConstantString
と
-lgnustep-base
を付けること。

で、コンパイル↓
$ make

それから実行↓
$ ./a.out

実行時に

2010-03-14 17:03:34.903 a.out[6391] Unknown time zone name `JST'.
2010-03-14 17:03:34.903 a.out[6391] Using time zone with absolute offset 0.

とか出るのは

/usr/lib/GNUstep/Libraries/gnustep-base/Versions/1.19/Resources/NSTimeZones/zones/JST

がないせい。なので、

# cd /usr/lib/GNUstep/Libraries/gnustep-base/Versions/1.19/Resources/NSTimeZones/zones/
# ln -s Japan JST
