gcc未定義的引用gd函數

我試圖編譯一個程序，但是當我運行make install時出現以下錯誤。gcc未定義的引用gd函數

gcc -fPIC -O3 -g -O2 -o treeviewer -L/usr/include -lm -lpng -ljpeg -lgd treeviewer.o tree.o fileio.o tree.o:

我已經用條命令sudo apt-get -y install libgd2-xpm-dev build-essential安裝libgd。文件夾/usr/include有文件gd.h。誰能告訴我我錯過了什麼？提前致謝。

如果不在gcc的默認目錄列表中，您可能需要列出libgd.a所在的目錄以及-L。

我做了列表目錄，以及並重新運行make文件，但還是同樣的結果。 'gcc -fPIC -O3 -g -O2 -o treeviewer -L/usr/include -L/usr/lib/x86_64-linux-gnu -lm -lpng -ljpeg -lgd treeviewer.o tree.o fileio.o' – Brkk

通過改變

gcc -fPIC -O3 -g -O2 -o treeviewer -L/usr/include -lm -lpng -ljpeg -lgd treeviewer.o tree.o fileio.o tree.o

解決它

gcc -fPIC -O3 -g -O2 treeviewer.o tree.o fileio.o tree.o -L/usr/include -lm -lpng -ljpeg -lgd -o treeviewer
