Ruby的has_header方法在哪里查找头文件？

在CentOS 5.7的盒子里，我在安装最新版本的mysql2 gem时遇到了麻烦; 它找不到errmsg.h： /usr/bin/ruby extconf.rb checking for rb_thread_blocking_region()… yes checking for rb_wait_for_single_fd()… no checking for mysql_query() in -lmysqlclient… yes checking for mysql.h… no checking for mysql/mysql.h… yes checking for errmsg.h… no —– errmsg.h is missing. please check your installation of mysql and try again. —– *** extconf.rb failed *** mysql头文件存在于/ usr / include / […]

用rvm安装ruby头文件

Travis CI使用RVM提供Ruby，但它似乎不包含标题： $ find /home/vagrant/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/i686-linux /home/vagrant/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/i686-linux /home/vagrant/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/i686-linux/zlib.so /home/vagrant/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/i686-linux/dl.so /home/vagrant/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/i686-linux/syck.so /home/vagrant/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/i686-linux/socket.so /home/vagrant/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/i686-linux/dbm.so /home/vagrant/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/i686-linux/pty.so /home/vagrant/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/i686-linux/strscan.so /home/vagrant/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/i686-linux/io /home/vagrant/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/i686-linux/io/console.so /home/vagrant/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/i686-linux/io/wait.so /home/vagrant/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/i686-linux/io/nonblock.so /home/vagrant/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/i686-linux/iconv.so /home/vagrant/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/i686-linux/enc /home/vagrant/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/i686-linux/enc/iso_8859_14.so /home/vagrant/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/i686-linux/enc/gb2312.so /home/vagrant/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/i686-linux/enc/iso_8859_16.so /home/vagrant/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/i686-linux/enc/windows_1251.so /home/vagrant/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/i686-linux/enc/euc_jp.so /home/vagrant/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/i686-linux/enc/iso_8859_4.so /home/vagrant/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/i686-linux/enc/iso_8859_1.so /home/vagrant/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/i686-linux/enc/trans /home/vagrant/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/i686-linux/enc/trans/japanese_euc.so /home/vagrant/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/i686-linux/enc/trans/emoji_sjis_softbank.so /home/vagrant/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/i686-linux/enc/trans/single_byte.so /home/vagrant/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/i686-linux/enc/trans/emoji_sjis_docomo.so /home/vagrant/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/i686-linux/enc/trans/utf8_mac.so /home/vagrant/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/i686-linux/enc/trans/gbk.so /home/vagrant/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/i686-linux/enc/trans/emoji.so /home/vagrant/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/i686-linux/enc/trans/japanese_sjis.so /home/vagrant/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/i686-linux/enc/trans/big5.so /home/vagrant/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/i686-linux/enc/trans/transdb.so /home/vagrant/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/i686-linux/enc/trans/japanese.so /home/vagrant/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/i686-linux/enc/trans/gb18030.so /home/vagrant/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/i686-linux/enc/trans/utf_16_32.so /home/vagrant/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/i686-linux/enc/trans/korean.so /home/vagrant/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/i686-linux/enc/trans/escape.so /home/vagrant/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/i686-linux/enc/trans/emoji_iso2022_kddi.so /home/vagrant/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/i686-linux/enc/trans/chinese.so /home/vagrant/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/i686-linux/enc/trans/iso2022.so /home/vagrant/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/i686-linux/enc/trans/emoji_sjis_kddi.so /home/vagrant/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/i686-linux/enc/encdb.so /home/vagrant/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/i686-linux/enc/utf_16le.so /home/vagrant/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/i686-linux/enc/gbk.so /home/vagrant/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/i686-linux/enc/iso_8859_8.so /home/vagrant/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/i686-linux/enc/euc_tw.so /home/vagrant/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/i686-linux/enc/koi8_r.so /home/vagrant/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/i686-linux/enc/iso_8859_9.so /home/vagrant/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/i686-linux/enc/utf_32le.so /home/vagrant/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/i686-linux/enc/big5.so […]

gem install找不到头文件

跟随talib_ruby的github自述文件： sudo port install ta-lib 完成。 接下来是麻烦开始的地方。 sudo env ARCHFLAGS=”-arch PLATFORM” gem install talib_ruby — –with-talib-include=ABSOLUTE_PATH_TO_TALIB_HEADERS –with-talib-lib=ABSOLUTE_PATH_TO_TALIB_LIBS 这个安装失败我相信因为显然它找不到ta_abstract.h文件 talib.c:2:25: error: ta_abstract.h: No such file or directory . . . many more errors 我在.bash_profile文件中包含以下内容： export ABSOLUTE_PATH_TO_TALIB_HEADERS=/opt/local/var/macports/software/ta-lib/0.4.0_0/opt/local/include/ta-lib export ABSOLUTE_PATH_TO_TALIB_LIBS=/opt/local/var/macports/software/ta-lib/0.4.0_0/opt/local/lib 实际上ta_abstract.h文件位于我在ABSOLUTE_PATH变量赋值中所说的位置。 是什么赋予了？ 更新： 当所有其他方法都失败时，与gem作者发送电子邮件通 他建议使用安装传递实际路径，而不是导出ABSOLUTE_PATH。 同时显式传入ARCHFLAGS =“ – arch x86_64”，适用于Snow Leopard。 安装仍然失败，但现在因为它有talib.c文件和其中的某些function的问题。
