|

If you want to build your app using go-sqlite3, you need gcc.
|
||||
However, after you have built and installed _go-sqlite3_ with `go install github.com/mattn/go-sqlite3` (which requires gcc), you can build your app without relying on gcc in future.
|
||||
|
||||
***Important: because this is a `CGO` enabled package you are required to set the environment variable `CGO_ENABLED=1` and have a `gcc` compile present within your path.***

# Compilation
|
||||
|
||||
- Want to build go-sqlite3 with libsqlite3 on my linux.
|
||||
This package requires `CGO_ENABLED=1` ennvironment variable if not set by default, and the presence of the `gcc` compiler.
|
||||
|
||||
Use `go build --tags "libsqlite3 linux"`
|
||||
If you need to add additional CFLAGS or LDFLAGS to the build command, and do not want to modify this package. Then this can be achieved by using the `CGO_CFLAGS` and `CGO_LDFLAGS` environment variables.
|
||||
|
||||
- Want to build go-sqlite3 with libsqlite3 on OS X.
|
||||
## Android
|
||||
|
||||
Install sqlite3 from homebrew: `brew install sqlite3`
|
||||
This package can be compiled for android.
|
||||
Compile with:
|
||||
|
||||
Use `go build --tags "libsqlite3 darwin"`
|
||||
```bash
|
||||
go build --tags "android"
|
||||
```
|
||||
|
||||
For more information see [#201](https://github.com/mattn/go-sqlite3/issues/201)
|
||||
|
||||
# ARM
|
||||
|
||||
To compile for `ARM` use the following environment.
|
||||
|
||||
```bash
|
||||
env CC=arm-linux-gnueabihf-gcc CXX=arm-linux-gnueabihf-g++ \
|
||||
CGO_ENABLED=1 GOOS=linux GOARCH=arm GOARM=7 \
|
||||
go build -v
|
||||
```

||||

|
||||
|
||||
# Cross Compile
|
||||
|
||||
This library can be cross-compiled.
|
||||
|
||||
In some cases you are required to the `CC` environment variable with the cross compiler.
|
||||
|
||||

|
||||
|
||||
## Docker
|
||||
|
||||
### Alpine
|
||||
|
||||
When building in an `alpine` container run the following command before building.
|
||||
|
||||
```
|
||||
apk add --update gcc musl-dev
|
||||
```
|
||||
|
||||
# Google Cloud Platform
|
||||
|
||||
Building on GCP is not possible because `Google Cloud Platform does not allow `gcc` to be executed.
|
||||
|
||||
Please work only with compiled final binaries.
|
||||
|
||||
## Linux
|
||||
|
||||
To compile this package on Linux you must install the development tools for your linux distribution.
|
||||
|
||||
To compile under linux use the build tag `linux`.
|
||||
|
||||
```bash
|
||||
go build --tags "linux"
|
||||
```
|
||||
|
||||
If you wish to link directly to libsqlite3 then you can use the `libsqlite3` build tag.
|
||||
|
||||
```
|
||||
go build --tags "libsqlite3 linux"
|
||||
```
|
||||
|
||||
### Fedora
|
||||
|
||||
```bash
|
||||
sudo yum groupinstall "Development Tools" "Development Libraries"
|
||||
```
|
||||
|
||||
### Ubuntu
|
||||
|
||||
```bash
|
||||
sudo apt-get install build-essential
|
||||
```
|
||||
|
||||
## Mac OSX
|
||||
|
||||
OSX should have all the tools present to compile this package, if not install XCode this will add all the developers tools.
|
||||
|
||||
Required dependency
|
||||
|
||||
```bash
|
||||
brew install sqlite3
|
||||
```
|
||||
|
||||
For OSX there is an additional package install which is required if you whish to build the `icu` extension.
|
||||
|
||||
This additional package can be installed with `homebrew`.
|
||||
|
||||
```bash
|
||||
brew upgrade icu4c
|
||||
```
|
||||
|
||||
To compile for Mac OSX.
|
||||
|
||||
```bash
|
||||
go build --tags "darwin"
|
||||
```
|
||||
|
||||
If you wish to link directly to libsqlite3 then you can use the `libsqlite3` build tag.
|
||||
|
||||
```
|
||||
go build --tags "libsqlite3 darwin"
|
||||
```

|
||||
|
||||
## Windows
|
||||
|
||||
To compile this package on Windows OS you must have the `gcc` compiler installed.
|
||||
|
||||
1) Install a Windows `gcc` toolchain.
|
||||
2) Add the `bin` folders to the Windows path if the installer did not do this by default.
|
||||
3) Open a terminal for the TDM-GCC toolchain, can be found in the Windows Start menu.
|
||||
4) Navigate to your project folder and run the `go build ...` command for this package.
|
||||
|
||||
For example the TDM-GCC Toolchain can be found [here](ttps://sourceforge.net/projects/tdm-gcc/).
|
||||
|
||||
## Errors
|
||||
|
||||
- Compile error: `can not be used when making a shared object; recompile with -fPIC`
|
||||
|
||||
When receiving a compile time error referencing recompile with `-FPIC` then you
|
||||
are probably using a hardend system.
|
||||
|
||||
You can copile the library on a hardend system with the following command.
|
||||
|
||||
```bash
|
||||
go build -ldflags '-extldflags=-fno-PIC'
|
||||
```
