Firebird是一种关系型数据库管理系统，它使用SQL（结构化查询语言）进行数据操作。与许多其他数据库系统相比，Firebird以其卓越的性能、稳定性和可扩展性而著称。
尝试在MAC下编译安装firebird
从下载页面下载，选最新的版本：https://sourceforge.net/projects/firebird/files/
这里有比较老的一篇mac安装指南：https://www.firebirdsql.org/file/documentation/papers_presentations/html/paper-fb-macosx.html
在MAC下查找
brew search firebird
==> Casks
firebird-emu这是一个TI-Nspire仿真器，不是我们需要的数据库。TI-Nspire CX是德州仪器公司于2011年推出的新一代彩屏图形计算器。
到firebird官网下载：https://firebirdsql.org/en/firebird-3-0/
下载源代码：
wget https://github.com/FirebirdSQL/firebird/releases/download/v3.0.12/Firebird-3.0.12.33787-0.tar.bz2
tar -xzvf Firebird-3.0.12.33787-0.tar.bz2进入目录，编译配置
./configure
如果报错说需要ICU，则安装
brew install icu4c安装之后提示
icu4c is keg-only, which means it was not symlinked into /usr/local,
because macOS provides libicucore.dylib (but nothing else).
If you need to have icu4c first in your PATH, run:
echo 'export PATH="/usr/local/opt/icu4c/bin:$PATH"' >> /Users/skywalk/.bash_profile
echo 'export PATH="/usr/local/opt/icu4c/sbin:$PATH"' >> /Users/skywalk/.bash_profile
For compilers to find icu4c you may need to set:
export LDFLAGS="-L/usr/local/opt/icu4c/lib"
export CPPFLAGS="-I/usr/local/opt/icu4c/include"
For pkg-config to find icu4c you may need to set:
export PKG_CONFIG_PATH="/usr/local/opt/icu4c/lib/pkgconfig"
==> node
Bash completion has been installed to:
/usr/local/etc/bash_completion.d按照提示应该输入这两句
export LDFLAGS="-L/usr/local/opt/icu4c/lib"
export CPPFLAGS="-I/usr/local/opt/icu4c/include"
export DYLD_LIBRARY_PATH=/path/to/icu/lib:$DYLD_LIBRARY_PATH
export LDFLAGS="/usr/local/opt/icu4c/lib"
export CPPFLAGS="/usr/local/opt/icu4c/include"
安装libtommath
brew install libtommath再次./configure
配置成功，提示
The Firebird3 package has been configured with the following options:
Raw devices : disabled
Service name : gds_db
Service port : 3050
GPRE modules : c_cxx.cpp
Install Dir : /usr/local/firebird
编译安装
make -j 4
make install
编译失败。先搁置
尝试编译5.0版本
下载编译firebird 5.0版本，没有成功，做了如下操作：
升级cmake
brew install cmake
./configure的时候报错
尝试安装vcpkg
不行。
尝试安装gcc
brew install gcc
不行
sh autogen.sh 试试
checking whether the C compiler works... no
configure: error: in `/Users/skywalk/Downloads/Firebird-5.0.1.1469-0-source':
configure: error: C compiler cannot create executables
尝试失败，先搁置。
尝试在MAC下直接安装firebird
原来firebird有mac的版本啊，直接下载5.0版本
wget https://github.com/FirebirdSQL/firebird/releases/download/v5.0.1/Firebird-5.0.1.1469-0-macos-x64.pkg下载完成后open
open Firebird-5.0.1.1469-0-macos-x64.pkg 这样就会打开mac下的安装程序，话说我以前都是用鼠标点的，原来直接命令行用open就行啊！
安装完成，测试一下：
看看服务是否启动了
ps -ax | grep firebird
71891 ?? 0:00.13 /Library/Frameworks/Firebird.framework/Versions/A/Resources/bin/firebird
这样证明firebird启动了
