I have such errors. I tried all variants, which Google can find out, but it didn`t help.
go build cmd/main.go

STEP_1. Trying to solve first error proj.h: No such file or directory:
First of all we need to install PROJ library:
sudo apt-get update
sudo apt-get install libproj-dev
root@2cabef130881:/app/src# apt-get update

libproj-dev is already the newest version (4.9.3-2).
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
After that we should find out file proj.h in our system. We should write a command find / -name proj.h 2>/dev/null, but I have no results after that. Typically the proj.h file is located in the /usr/include directory
But he's not there...
If the proj.h file is available, then in our case, go-proj should know about the presence of the PROJ library. This is usually configured through the CGO_CFLAGS and CGO_LDFLAGS environment variables.
In theory it should be:
export CGO_CFLAGS="-I/usr/include"
export CGO_LDFLAGS="-L/usr/lib"
In my code I use import "github.com/omniscale/go-proj/v2" maybe we should write comething new in library ?
STEP_2. Trying to solve first error `fatal error: gdal.h: No such file or directory
I tried to solve this problem, like here Install GDAL on LINUX Ubuntu 20.04.4LTS for python but it didnt help.
I tried to fix troubles with gdall library, I installed on OS:
sudo add-apt-repository ppa:ubuntugis/ppa
sudo apt-get update
sudo apt-get install gdal-bin
sudo apt-get install libgdal-dev
But it didnt help. Whitch GDAL version I have at present time:
apt list --installed | grep "gdal"
WARNING: apt does not have a stable CLI interface. Use with caution in scripts.
gdal-bin/bionic,now 2.2.3+dfsg-2 arm64 [installed]
gdal-data/bionic,now 2.2.3+dfsg-2 all [installed,automatic]
libgdal-dev/bionic,now 2.2.3+dfsg-2 arm64 [installed]
libgdal20/bionic,now 2.2.3+dfsg-2 arm64 [installed,automatic]
gdalinfo --version
GDAL 2.2.3, released 2017/11/20
If we speak about another libraries, which we need to install near GDAL, I installed them in Docker container via command:
RUN apt-get update && apt-get upgrade -yy && apt-get install -yy \
wget \
git \
build-essential \
git \
clang-3.8 \
libpng-dev \
libopencv-dev \
libgeos-dev \
libproj-dev && \
apt remove cmake -y && \
pip3 install --upgrade pip && \
pip3 install cmake --upgrade && \
apt autoremove -y
