[5.2.0] When build tag have dbg, works well, but when have no dbg, it have problems.

Command: bazelisk build --tool_tag=ijwb:AndroidStudio 
--output_groups=+android_deploy_info 
--curses=no --color=yes --progress_in_terminal_title=no
 -c opt --strip=always --config=android_arm64 -s --fission=no

The second command compare with the first one , it added -c dbg, and --build_event_binary_file difference.

This is my project code:

                glGenTextures(1, &brdfLUTMap);
                glActiveTexture(GL_TEXTURE2);
                glBindTexture(GL_TEXTURE_2D, brdfLUTMap);
                glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB16F, 512, 512, 0, GL_RGB, GL_FLOAT, 0);
                // be sure to set wrapping mode to GL_CLAMP_TO_EDGE
                glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_CLAMP_TO_EDGE);
                glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_CLAMP_TO_EDGE);
                glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR);
                glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR);

                // then re-configure capture framebuffer object and render screen-space quad with BRDF shader.
                glBindFramebuffer(GL_FRAMEBUFFER, captureFBO);
                glBindRenderbuffer(GL_RENDERBUFFER, captureRBO);
                glRenderbufferStorage(GL_RENDERBUFFER, GL_DEPTH_COMPONENT24, 512, 512);
                glFramebufferRenderbuffer(GL_FRAMEBUFFER, GL_DEPTH_ATTACHMENT, GL_RENDERBUFFER, captureRBO);
                checkGLError("--glFramebufferRenderbuffer ");
                glFramebufferTexture2D(GL_FRAMEBUFFER, GL_COLOR_ATTACHMENT0, GL_TEXTURE_2D, brdfLUTMap, 0);
                glViewport(0, 0, 512, 512);
                brdfShader.use();
                glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
                renderQuad();
                glBindFramebuffer(GL_FRAMEBUFFER, 0);

If i use the first command , i can sampling data from brdfLUTMap, if i use the second command, can't sampling data from brdfLUTMap. it's very wired , because other textures have no problem using both two command.

Hello @wingdi, Could you please elaborate your use case and provide complete steps to reproduce the above error. Thanks!

[wingdi]

@sgowroji Very thanks for your reply. It's nice to meet you at this project.

First i bind FBO with Texture , and render data to this Texture:

                glGenTextures(1, &brdfLUTMap);
                glActiveTexture(GL_TEXTURE2);
                glBindTexture(GL_TEXTURE_2D, brdfLUTMap);
                glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB16F, 512, 512, 0, GL_RGB, GL_FLOAT, 0);
                glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_CLAMP_TO_EDGE);
                glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_CLAMP_TO_EDGE);
                glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR);
                glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR);

                glBindFramebuffer(GL_FRAMEBUFFER, captureFBO);
                glBindRenderbuffer(GL_RENDERBUFFER, captureRBO);
                glRenderbufferStorage(GL_RENDERBUFFER, GL_DEPTH_COMPONENT24, 512, 512);
                glFramebufferRenderbuffer(GL_FRAMEBUFFER, GL_DEPTH_ATTACHMENT, GL_RENDERBUFFER, captureRBO);
                glFramebufferTexture2D(GL_FRAMEBUFFER, GL_COLOR_ATTACHMENT0, GL_TEXTURE_2D, brdfLUTMap, 0);
                LOG(ERROR) << "brdfFrameBufferStatus(36053-Normal) "  << glCheckFramebufferStatus(GL_FRAMEBUFFER);
                checkGLError("--brdfLUTMap ");

                glViewport(0, 0, 512, 512);
                brdfShaderProgram.use();
                glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
                
                GLuint quadVAO;
                GLuint quadVBO;
                if (quadVAO == 0){
                    float quadVertices[] = {
                            // positions        // texture Coords
                            -1.0f,  1.0f, 0.0f, 0.0f, 1.0f,
                            -1.0f, -1.0f, 0.0f, 0.0f, 0.0f,
                            1.0f,  1.0f, 0.0f, 1.0f, 1.0f,
                            1.0f, -1.0f, 0.0f, 1.0f, 0.0f,
                    };
                    // setup plane VAO
                    glGenVertexArrays(1, &quadVAO);
                    glGenBuffers(1, &quadVBO);
                    glBindVertexArray(quadVAO);
                    glBindBuffer(GL_ARRAY_BUFFER, quadVBO);
                    glBufferData(GL_ARRAY_BUFFER, sizeof(quadVertices), &quadVertices, GL_STATIC_DRAW);
                    glEnableVertexAttribArray(0);
                    glVertexAttribPointer(0, 3, GL_FLOAT, GL_FALSE, 5 * sizeof(float), (void*)0);
                    glEnableVertexAttribArray(1);
                    glVertexAttribPointer(1, 2, GL_FLOAT, GL_FALSE, 5 * sizeof(float), (void*)(3 * sizeof(float)));
                }
                glBindVertexArray(quadVAO);
                glDrawArrays(GL_TRIANGLE_STRIP, 0, 4);
                glBindBuffer(GL_ARRAY_BUFFER, 0);
                glBindVertexArray(0);

                glBindTexture(GL_TEXTURE_2D, 0);
                glBindRenderbuffer(GL_RENDERBUFFER, 0);
                glBindFramebuffer(GL_FRAMEBUFFER, 0);

                checkGLError("--brdfLUTMap ");

Then sampling data from this Texture:

                glActiveTexture(GL_TEXTURE2);
                glBindTexture(GL_TEXTURE_2D, brdfLUTMap);
                ... 
                glDrawElements(mesh_3d.primitive_type, mesh_3d.index_buffer.size(),
                               GL_UNSIGNED_INT, mesh_3d.index_buffer.data());

When build with dbg , it works well, but if build without dbg, sampling data from brdfLUTMap is zero.
Using bazel-v5.0.0 and bazel-v5.2.0 have same problem.

Hi @wingdi,

It doesn't seem to me like this is an issue with the Android rules or Android build process in general; it reads more like a build configuration issue.

Have you tried running your test with --subcommands to see what Bazel is doing differently between your two builds? I usually do something like bazel build //my:target --subcommands 2>&1 | tee log.log so I can pipe the stdout + stderr output to a log file.
