- 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?
回答1:
Make sure you've installed both libpq-dev\ and postgresql-server-dev-all (or specific version e.g. postgresql-server-dev-9.4)
$ dpkg --get-selections | grep -e "libpq-dev\|postgresql-server-dev"
in case you're missing some package
apt-get install libpq-dev postgresql-server-dev-all
should fix it.

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}" )

On Ubuntu you can also work around that issue by calling cmake with having PostgreSQL_TYPE_INCLUDE_DIR defined like this:
cmake -DPostgreSQL_TYPE_INCLUDE_DIR=/usr/include/postgresql/
On Ubuntu/Debian, starting with PostgreSQL 9.3 the header file pg_type.h is moved to a separate package (from libpq-dev to postgresql-server-dev) and consequently the file pg_type.h is moved to a new location

From Linux Mint 17.3 ("Rosa") with PostgreSQL 9.3, I had to adjust ilia choly's solution (interestingly, the suggested postgres entry in the list was already present in the file, but wasn't enough to fix things).
I had to edit /usr/share/cmake-2.8/Modules/FindPostgreSQL.cmake around line 114 and add postgresql/9.3 so that the find_path call looks like
find_path(PostgreSQL_TYPE_INCLUDE_DIR NAMES catalog/pg_type.h PATHS # Look in other places. ${PostgreSQL_ROOT_DIRECTORIES} PATH_SUFFIXES postgresql/9.3 postgresql pgsql/server postgresql/server include/server # Help the user find it if we cannot. DOC "The ${PostgreSQL_INCLUDE_DIR_MESSAGE}" )
