FindPostgreSQL.cmake将不能在ubuntu上工作 [英] FindPostgreSQL.cmake won't work on ubuntu

问题描述

• Ubuntu 12.04


• CMake 2.8.9


• Postgresql 9.2.2

c / c / c / c / c / c / c / c / c / c / c / c / c / postgresql / libpq-fe.h 。




这是我在 CMakeLists.txt 中所拥有的：

  find_package（PostgreSQL REQUIRED）
  

我得到：

  CMake错误在/usr/share/cmake-2.8/Modules/FindPackageHandleStandardArgs.cmake:97（MESSAGE）： 
无法找到PostgreSQL（缺少：PostgreSQL_TYPE_INCLUDE_DIR）（找到
版本9.2.2）
调用堆栈（最近调用）
 / usr / share / 2.8 / Modules / FindPackageHandleStandardArgs.cmake：288（_FPHSA_FAILURE_MESSAGE）
 /usr/share/cmake-2.8/Modules/FindPostgreSQL.cmake:155（find_package_handle_standard_args）
 CMakeLists.txt：7（find_package）
 

我在调用 find_package 之前添加了以下行，但它didn

 设置（PostgreSQL_ADDITIONAL_VERSIONS9.2.2）
设置（PostgreSQL_ADDITIONAL_SEARCH_PATHS $ { PostgreSQL_ADDITIONAL_SEARCH_PATHS}/ usr / include / postgresql）
  



我还尝试了 PostgreSQL_TYPE_INCLUDE_DIR ，但没有找到任何东西。我还可以尝试什么？

解决方案

经过一些更多的调试后，我发现它正在卡住试图找到 pg_type.h





此文件位于 /usr/include/postgresql/catalog/pg_types.h ，但模块希望在 /usr/include/postgresql/server/catalog/pg_types.h

  find_path（PostgreSQL_TYPE_INCLUDE_DIR 
 NAMES catalog / pg_type.h 
 PATHS 
＃查看其他地方
 $ {PostgreSQL_ROOT_DIRECTORIES} 
 PATH_SUFFIXES 
 pgsql / server 
 postgresql / server 
 include / server 
＃帮助用户找到它如果我们不能
 DOC $ {PostgreSQL_INCLUDE_DIR_MESSAGE}
）
  



如果我添加 postgresql 至 PATH_SUFFIXES

  find_path PostgreSQL_TYPE_INCLUDE_DIR 
 NAMES目录/ pg_type.h 
 PATHS 
＃查看其他地方
 $ {PostgreSQL_ROOT_DIRECTORIES} 
 PATH_SUFFIXES 
 postgresql 
 pgsql / server 
 postgresql / server 
 include / server 
＃帮助用户找到它，如果我们不能。 
 DOCThe $ {PostgreSQL_INCLUDE_DIR_MESSAGE}
）
  




• Ubuntu 12.04
• CMake 2.8.9
• Postgresql 9.2.2

I'm trying to get the FindPostgreSQL module to find /usr/include/postgresql/libpq-fe.h.

Here's what I have in my CMakeLists.txt:

find_package(PostgreSQL REQUIRED)

This is the error I get:

CMake Error at /usr/share/cmake-2.8/Modules/FindPackageHandleStandardArgs.cmake:97 (MESSAGE):
  Could NOT find PostgreSQL (missing: PostgreSQL_TYPE_INCLUDE_DIR) (found
  version "9.2.2")
Call Stack (most recent call first):
  /usr/share/cmake-2.8/Modules/FindPackageHandleStandardArgs.cmake:288 (_FPHSA_FAILURE_MESSAGE)
  /usr/share/cmake-2.8/Modules/FindPostgreSQL.cmake:155 (find_package_handle_standard_args)
  CMakeLists.txt:7 (find_package)

I added the following lines before calling find_package but it didn't seem to have any effect.

set(PostgreSQL_ADDITIONAL_VERSIONS "9.2.2")
set(PostgreSQL_ADDITIONAL_SEARCH_PATHS ${PostgreSQL_ADDITIONAL_SEARCH_PATHS} "/usr/include/postgresql")

I also tried googling for PostgreSQL_TYPE_INCLUDE_DIR but didn't find anything. What else can I try?

解决方案

After a bit more debugging I figured out that it's getting stuck trying to find pg_type.h

This file is located in /usr/include/postgresql/catalog/pg_types.h but the module is expecting to find it in /usr/include/postgresql/server/catalog/pg_types.h

find_path(PostgreSQL_TYPE_INCLUDE_DIR
  NAMES catalog/pg_type.h
  PATHS
   # Look in other places.
   ${PostgreSQL_ROOT_DIRECTORIES}
  PATH_SUFFIXES
    pgsql/server
    postgresql/server
    include/server
  # Help the user find it if we cannot.
  DOC "The ${PostgreSQL_INCLUDE_DIR_MESSAGE}"
)

It works if I add postgresql to the PATH_SUFFIXES

find_path(PostgreSQL_TYPE_INCLUDE_DIR
  NAMES catalog/pg_type.h
  PATHS
   # Look in other places.
   ${PostgreSQL_ROOT_DIRECTORIES}
  PATH_SUFFIXES
    postgresql
    pgsql/server
    postgresql/server
    include/server
  # Help the user find it if we cannot.
  DOC "The ${PostgreSQL_INCLUDE_DIR_MESSAGE}"
)
