sql.h header file missing though unixODBC is installed
You need to install the unixodbc-dev
package to get the development header files.
sudo apt-get install unixodbc-dev
The -dev
packages contain the require header files required to compile and build programs using these headers to make calls to the library. The library files themselves would be part of the regular package i.e. unixodbc
in your case.
If you want to know which package provides a certain file, you could use apt-file
:
sudo apt-file update
sudo apt-file find sql.h

I am on an up-to-date Ubuntu 12.04 system. I have unixodbc (v2.2.14 from ubuntu repos), MySQL and its relevant drivers installed. Also connected to a valid DSN. Verified by issuing
isql DBName UName passwd
.I am trying to compile a C application that interacts with the database using ODBC. Almost everywhere I searched seemed to indicate that I should have "sql.h" installed somewhere. A
find / -iname sql.h -print
showed I don't have it.So my question is: where is it? Did something go wrong with the install (no errors were reported though)? And what steps do you recommend? Reinstallation? Compilation from source code (the latest version?)?

Richard about 11 yearsThanks a lot Tuxdude. I knew it was something quite trivial. And thanks for the tip on
apt-file
. Makes searching easier -
Richard about 11 yearsAs an aside, for future viewers of the question
pkg-config
can help find the relevant include directories, and libraries for use at compile time and link time. Refer the man page for more details. Note that it must "know" about them. Library packages from repos usually are configured to install in manner so that it makes "known" the details topkg-config

sudo apt-file find sql.h
on Ubuntu 14.04 contains this lineunixodbc-dev: /usr/include/sql.h

Diego Jancic over 7 yearsJust for reference, a similar error is reported here: stackoverflow.com/a/31360218/72350, and the solution described there also works for AWS Elastic Beanstalk:
sudo yum install unixODBC-devel
