问题:

I tried to compile test application for MonetDB under Ubuntu 14.04 LTS Trusty Tahr. I followed the download instructions from official site, installation was successful, then I installed a bunch of other packages in order to copmpile it. Now when I try to compile and link test application I get the following errors:

libtool: compile:  gcc -c -I/usr/include/monetdb test.c  -fPIC -DPIC -o .libs/test.o
libtool: compile:  gcc -c -I/usr/include/monetdb test.c -o test.o >/dev/null 2>&1
libtool: link: gcc -o test test.o  -lmapi -lstream -lssl -lcrypto -lcurl -lz
test.o: In function `die':

collect2: error: ld returned 1 exit status

What I'm doing wrong? What should I additionally install or change in compilation options for successful linking of test example?

回答1:

I was able to compile the example on Ubuntu 14.04 with MonetDB installed from the Ubuntu binary packages after installing the (additional) package libmonetdb-client-dev with the following command:

gcc test.c -I /usr/include/monetdb -lmapi

Did you compile and install MonetDB from source? In this case, which prefix was used?

Here how it worked using ubuntu 18.04

gcc main.c -I /usr/include/monetdb -lmapi -lssl -lcrypto -lstream -lcurl -llzma -lbz2
