I tried to compile test application ( https://www.monetdb.org/Documentation/Manuals/SQLreference/Programming/MAPI) for MonetDB under Ubuntu 14.04 LTS Trusty Tahr. I followed the download instructions from official site (https://www.monetdb.org/downloads/deb), 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 libtool: link: gcc -o test test.o -lmapi -lstream -lssl -lcrypto -lcurl -lz test.o: In function `die': test.c:(.text+0x1c): undefined reference to `mapi_explain_query' test.c:(.text+0x27): undefined reference to `mapi_result_error' test.c:(.text+0x3f): undefined reference to `mapi_explain_result' test.c:(.text+0x4a): undefined reference to `mapi_next_result' test.c:(.text+0x5a): undefined reference to `mapi_close_handle' test.c:(.text+0x65): undefined reference to `mapi_destroy' test.c:(.text+0x81): undefined reference to `mapi_explain' test.c:(.text+0x8c): undefined reference to `mapi_destroy' test.o: In function `query': test.c:(.text+0xde): undefined reference to `mapi_query' test.c:(.text+0xf2): undefined reference to `mapi_error' test.o: In function `update': test.c:(.text+0x133): undefined reference to `mapi_close_handle' test.o: In function `main': test.c:(.text+0x190): undefined reference to `mapi_connect' test.c:(.text+0x1a0): undefined reference to `mapi_error' test.c:(.text+0x222): undefined reference to `mapi_fetch_field' test.c:(.text+0x23a): undefined reference to `mapi_fetch_field' test.c:(.text+0x266): undefined reference to `mapi_fetch_row' test.c:(.text+0x276): undefined reference to `mapi_close_handle' test.c:(.text+0x282): undefined reference to `mapi_destroy' collect2: error: ld returned 1 exit status ./t.sh: 11: ./t.sh: ./test: not found What I'm doing wrong? What should I additionally install or change in compilation options for successful linking of test example? Best regards and thanks in advance, Ivan
