rắc rối cố gắng xây dựng OpenGL mã ví dụ superbible

Question

Vì vậy, tôi có ấn bản thứ 6 superbible, và đang cố gắng để cmake và làm cho khuôn khổ mã ví dụ, nhưng nhận được lỗi này:

tôi đang thiếu gì? Theo như tôi có thể nói tôi đã cài đặt tất cả các phụ thuộc.

Answer 1

Có một lỗi trong CMakeLists.txt tại dòng 13. (https://github.com/openglsuperbible/sb6code/blob/master/CMakeLists.txt)

Thay đổi "elif (UNIX)" thành "elseif (UNIX)" và sẽ ổn.

Answer 2

như @AndonMColeman đề xuất, bạn cần -lGL và -ldlvào cuối trong danh sách thư viện. Sử dụng macro target_link_libraries cho việc này.

Nếu bạn cung cấp CMakeLists.txt từ dự án của bạn sẽ dễ dàng hơn nhiều để đề nghị bạn một chuỗi chính xác để thêm/thay đổi;)
