Question

尝试仅在Debian 9上编译Eiffel_18.07 / examples / store / esql /我遇到以下错误：

In file included from od243.c:202:0,
                 from big_file_C8_c.c:42:
/opt/Eiffel_18.07/library/store/dbms/rdbms/odbc/Clib/odbc.h:27:17: fatal error: sql.h: No such file or directory

                 ^
compilation terminated.

Makefile:72: recipe for target 'C8/Cobj8.o' failed
make: *** [C8/Cobj8.o] Error 2
make: *** Waiting for unfinished jobs....

apt-get install unixodbc unixodbc-dev odbc-postgresql 让我进一步去

gcc: error: /opt/Eiffel_18.07/library/store/spec/linux-x86-64/lib/libodbc.a: No such file or directory
Makefile:177: recipe for target 'esql' failed

当我尝试进入/opt/Eiffel_18.07/library/store/dbms/rdbms/odbc/Clib时，我将能够生成一些代码来使它在/opt/Eiffel_18.07/library/store/install之后进入/opt/Eiffel_18.07/library/store/dbms/rdbms/odbc/Clib，并尝试sudo /opt/Eiffel_18.07/studio/spec/linux-x86-64/bin/finish_freezing -library

cp: cannot stat '/usr/include/eiffelstudio-18.07/config.sh': No such file or directory
Can't find config.sh.
Makefile.SH: 6: .: Can't open ./config.sh

作为埃菲尔铁塔的粉丝，它似乎并没有开箱即用，而且我也没有找到足够的文档来使其正常运行：-（）

Answer 1

以下是一系列步骤，使我可以在 Ubuntu 16.04 上构建示例：

下载 EiffelStudio 并将其解压缩到新目录中（让我们将绝对路径表示为#ES#）。

设置环境变量：

export ISE_EIFFEL=#ES#
export ISE_PLATFORM=linux-x86-64
export PATH=$PATH:$ISE_EIFFEL/studio/spec/$ISE_PLATFORM/bin

这些命令假定为bash，在使用另一个shell时将其替换为等效项。

安装软件包unixodbc-dev：
```
sudo apt-get install unixodbc-dev
```
编译Eiffel库 store 的C代码：
```
cd ${ISE_EIFFEL}/library/store/dbms/rdbms/odbc/Clib
finish_freezing -library
```
注意：除非将 EiffelStudio 安装到没有普通用户写入权限的路径，否则无需在finish_freezing之前为sudo加上前缀。否则（例如，对于 Debian 9 上问题的原始发布者，其中 EiffelStudio 已安装在/opt下），必须提高权限：
```
sudo -i
cd ${ISE_EIFFEL}/library/store/dbms/rdbms/odbc/Clib
finish_freezing -library
exit
```

编译示例esql：

cd ${ISE_EIFFEL}/examples/store/esql
ec -c_compile -config esql.ecf -target esql_odbc

运行已编译的可执行文件：
```
./EIFGENs/esql_odbc/W_code/esql
```

Answer 2

以root身份登录改变了我的问题，而不仅仅是对finish_freezing命令进行了sudo

    sudo -i

然后

    cd ${ISE_EIFFEL}/library/store/dbms/rdbms/odbc/Clib
    finish_freezing -library
